Delete user ribbon from file

I have .xlsb file with user ribbon (i made it in "Custom UI Editor For Microsoft Office").

I want automatically delete (or hide) this ribbon from file (with VBA). Is it possible?

For this demonstration, you need CustomUI Editor and Excel(Obviously)

Create a new workbook and save it as say AlexExample.xlsm

[A] Open VBE, and insert a module. Paste this code in the module

Option Explicit

Dim Ribn As IRibbonUI
Public RibnTag As String

Sub RibbonOnLoad(ribbon As IRibbonUI)   
    Set Ribn = ribbon
End Sub

Sub GetVisible(control As IRibbonControl, ByRef visible)
    Select Case RibnTag
    Case "ShowTab": visible = True
    Case "HideTab": visible = False
    End Select
End Sub

Sub ShowMyRibbonTab()
    RibnTag = "ShowTab"
    If Not Ribn Is Nothing Then
        Ribn.Invalidate
    Else
        MsgBox "Couldn't get the ribbon object. Please close and restart the workbook"
    End If
End Sub

Sub HideMyRibbonTab()
    RibnTag = "HideTab"
    If Not Ribn Is Nothing Then
        Ribn.Invalidate
    Else
        MsgBox "Couldn't get the ribbon object. Please close and restart the workbook"
    End If
End Sub

[B] Open the ThisWorkbook code area and paste this code

Option Explicit

Private Sub Workbook_Open()
    RibnTag = "ShowTab"
End Sub

[C] Go to the sheet and create 2 buttons (Form Control). SHOW and HIDE as shown below. Right click on the button and assign the macro ShowMyRibbonTab to SHOW and HideMyRibbonTab to HIDE

[D] Next Open CustomUI Editor and open the Excel File from there. Insert customUI.xml and paste the below code there.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<customUI onLoad="RibbonOnLoad" 
xmlns="http://schemas.microsoft.com/office/2006/01/customui">
<ribbon>
    <tabs>
      <tab id="MyCustomTab" label="AlexsTab" getVisible="GetVisible" tag="AlexsTab" >
    </tab>
</tabs>
</ribbon>
</customUI>

Save and close the file and you are done.
