When provisioning a Cosmos DB - Gremlin API from PowerShell, is there a way to set the capacity mode to Serverless?

When I create a Cosmos DB - Gremlin API from the Azure Portal there is an option to set the capacity mode to serverless:

However, when I look through the documentation for doing the same through PowerShell, I cannot find something that can do this.

Here is a way to do this that some folk at Azure sent over:

$resourceGroupName = "my-rg" 
$accountLocation = "Central US"
$accountName = "my-account"
$failoverLocations = @(
     @{ "locationName"="Central US"; "failoverPriority"=0 }
 )
$capabilities= @(@{"name"="EnableServerless"},@{"name"="EnableGremlin"})
$CosmosDBProperties = @{
     "databaseAccountOfferType"="Standard";
     "locations"=$failoverLocations;
     "capabilities"=$capabilities;
 }
New-AzResource -ResourceType "Microsoft.DocumentDb/databaseAccounts" `
     -ApiVersion "2019-12-12" -ResourceGroupName $resourceGroupName `
     -Location $accountLocation -Name $accountName -PropertyObject $CosmosDBProperties

Note that the cmdlet is New-AzResource not New-AzCosmosDBAccount.
