HELP! with Powershell SetPhysicalPresenceRequest method of the Win32_Tpm class

Question

Hello Can someone please help me with Enabling TPM using Powershell SetPhysicalPresenceRequest method of the Win32_Tpm class.

I have used below script in SCCM Task Sequence, the Task Sequence seems to execute successfully - but the TPM is still disabled.

$tpm = Get-WmiObject -class Win32_Tpm -namespace root\CIMV2\Security\MicrosoftTpm
$tpm.SetPhysicalPresenceRequest(14)

Also even tried below one liner:

powershell.exe -command "& {(Get-WMIObject -Namespace root/cimv2/Security/MicrosoftTPM -class Win32_TPM).SetPhysicalPresenceRequest(10)}"

powershell.exe -executionpolicy bypass -command "(Get-WmiObject -Namespace "root\CIMV2\Security\MicrosoftTpm" -Class Win32_TPM).SetPhysicalPresenceRequest(10)"

Tried with SetPhysicalPresenceRequest(6), SetPhysicalPresenceRequest(16) - as well. But the TPM is never enabled.

Can someone please help.

Thank you very much

Hi,

I'm not familiar with enabling TPM in SCCM task sequence but Initialize-Tpm is part of the provisioning process for TPM.

Please try to initialize TPM before SetPhysicalPresenceRequest. If the issue persists, please let me know.
How do you guys handle TPM in task sequences?

Initialize TPM:
powershell.exe Initialize-Tpm
