Create an Azure VM with an unmanaged disk

I'm trying to create an Azure VM with an unmanaged disk via PowerShell since managed disks aren't supported in Azure Government yet.

None of the documentation I could find for PowerShell VM creation references managed or unmanaged disks and the default seems to be managed disks. My VM creation fails with the following error:

New-AzureRmVM : Managed Disks are not supported in this region.

ErrorCode: BadRequest

Here's the script I'm using:

$location = "USGovTexas"

New-AzureRmResourceGroup -Name myResourceGroup -Location $location

# Create a subnet configuration
$subnetConfig = New-AzureRmVirtualNetworkSubnetConfig -Name mySubnet -AddressPrefix 192.168.1.0/24

# Create a virtual network
$vnet = New-AzureRmVirtualNetwork -ResourceGroupName myResourceGroup -Location $location `
    -Name MYvNET -AddressPrefix 192.168.0.0/16 -Subnet $subnetConfig

# Create a public IP address and specify a DNS name
$pip = New-AzureRmPublicIpAddress -ResourceGroupName myResourceGroup -Location $location `
    -AllocationMethod Static -IdleTimeoutInMinutes 4 -Name "mypublicdns$(Get-Random)"

# Create an inbound network security group rule for port 3389
$nsgRuleRDP = New-AzureRmNetworkSecurityRuleConfig -Name myNetworkSecurityGroupRuleRDP  -Protocol Tcp `
    -Direction Inbound -Priority 1000 -SourceAddressPrefix * -SourcePortRange * -DestinationAddressPrefix * `
    -DestinationPortRange 3389 -Access Allow

# Create an inbound network security group rule for port 80
$nsgRuleWeb = New-AzureRmNetworkSecurityRuleConfig -Name myNetworkSecurityGroupRuleWWW  -Protocol Tcp `
    -Direction Inbound -Priority 1001 -SourceAddressPrefix * -SourcePortRange * -DestinationAddressPrefix * `
    -DestinationPortRange 80 -Access Allow

# Create a network security group
$nsg = New-AzureRmNetworkSecurityGroup -ResourceGroupName myResourceGroup -Location $location `
    -Name myNetworkSecurityGroup -SecurityRules $nsgRuleRDP,$nsgRuleWeb

# Create a virtual network card and associate with public IP address and NSG
$nic = New-AzureRmNetworkInterface -Name myNic -ResourceGroupName myResourceGroup -Location $location `
    -SubnetId $vnet.Subnets[0].Id -PublicIpAddressId $pip.Id -NetworkSecurityGroupId $nsg.Id

# Define a credential object
$cred = Get-Credential

# Create a virtual machine configuration
$vmConfig = New-AzureRmVMConfig -VMName myVM -VMSize Standard_DS2_v2 | `
    Set-AzureRmVMOperatingSystem -Windows -ComputerName myVM -Credential $cred | `
    Set-AzureRmVMSourceImage -PublisherName MicrosoftWindowsServer -Offer WindowsServer `
    -Skus 2016-Datacenter -Version latest | Add-AzureRmVMNetworkInterface -Id $nic.Id

# Create the virtual machine
New-AzureRmVM -ResourceGroupName myResourceGroup -Location $location -VM $vmConfig

We can use this script to create Azure windows VM with unmanaged disk:

$location = "USGovTexas"
$rgname = "myResourceGroup"
New-AzureRmResourceGroup -Name myResourceGroup -Location $location

# Create a subnet configuration
$subnetConfig = New-AzureRmVirtualNetworkSubnetConfig -Name mySubnet -AddressPrefix 192.168.1.0/24

# Create a virtual network
$vnet = New-AzureRmVirtualNetwork -ResourceGroupName myResourceGroup -Location $location `
    -Name MYvNET -AddressPrefix 192.168.0.0/16 -Subnet $subnetConfig

# Create a public IP address and specify a DNS name
$pip = New-AzureRmPublicIpAddress -ResourceGroupName myResourceGroup -Location $location `
    -AllocationMethod Static -IdleTimeoutInMinutes 4 -Name "mypublicdns$(Get-Random)"

# Create an inbound network security group rule for port 3389
$nsgRuleRDP = New-AzureRmNetworkSecurityRuleConfig -Name myNetworkSecurityGroupRuleRDP  -Protocol Tcp `
    -Direction Inbound -Priority 1000 -SourceAddressPrefix * -SourcePortRange * -DestinationAddressPrefix * `
    -DestinationPortRange 3389 -Access Allow

# Create an inbound network security group rule for port 80
$nsgRuleWeb = New-AzureRmNetworkSecurityRuleConfig -Name myNetworkSecurityGroupRuleWWW  -Protocol Tcp `
    -Direction Inbound -Priority 1001 -SourceAddressPrefix * -SourcePortRange * -DestinationAddressPrefix * `
    -DestinationPortRange 80 -Access Allow

# Create a network security group
$nsg = New-AzureRmNetworkSecurityGroup -ResourceGroupName myResourceGroup -Location $location `
    -Name myNetworkSecurityGroup -SecurityRules $nsgRuleRDP,$nsgRuleWeb

# Create a virtual network card and associate with public IP address and NSG
$nic = New-AzureRmNetworkInterface -Name myNic -ResourceGroupName myResourceGroup -Location $location `
    -SubnetId $vnet.Subnets[0].Id -PublicIpAddressId $pip.Id -NetworkSecurityGroupId $nsg.Id

# Define a credential object
$cred = Get-Credential

#VM config

$vm = New-AzureRmVMConfig -VMName $vmName -VMSize $vmSize
$pubName = ”MicrosoftWindowsServer”
$offerName = ”WindowsServer”
$skuName = ”2016-Datacenter”
$vm = Set-AzureRmVMOperatingSystem -VM $vm -Windows -ComputerName $vmName -Credential $cred
$vm = Set-AzureRmVMSourceImage -VM $vm -PublisherName $pubName -Offer $offerName -Skus $skuName -Version "latest"

$vm = Set-AzureRmVMOSDisk -VM $vm -Name $diskName -VhdUri $OSDiskUri -CreateOption fromImage 

# Create the virtual machine
