Set-AzVmssUefi
Modifies UEFI properties of gen 2 virtual machines that are part of virtual machine scale sets
Syntax
Default (Default)
Set-AzVmssUefi
[-VirtualMachineScaleSet] <PSVirtualMachineScaleSet>
[[-EnableVtpm] <Boolean>]
[[-EnableSecureBoot] <Boolean>]
[-DefaultProfile <IAzureContextContainer>]
[<CommonParameters>]
Description
The Set-AzVmssUefi cmdlet modifies UEFI properties of virtual machines in a virtual machine scale set.
Examples
Example 1
$VMSS = Get-AzVmss -ResourceGroupName "ResourceGroup11" -VMScaleSetName "ContosoVM07"
Set-AzVmssUefi -VirtualMachineScaleSet $VMSS -EnableVtpm $true -EnableSecureBoot $true
The first command gets the virtual machine scale set named ContosoVM07 by using Get-AzVmss. The command stores it in the $VMSS variable. The second command modifies the UEFI settings to enable SecureBoot and vTPM on virtual machines in $VMSS. The command passes the result to the Update-AzVmss cmdlet, which implements your changes. A change to the cashing mode causes the virtual machine to restart.
