Solved Clear TPM when doing clean install of Windows 11

Do I need to clear the TPM from UEFI setup after secure erasing SSD from UEFI setup and before clean installing Windows 11 using a bootable installation media?

You don't need to clear the TPM.

Only if you have problem with installation.

You don't need to - but it is a good idea since you are cleanly installing anyway.

I've only cleared the TPM once. I was having trouble using my pin number to log-in to my laptop. Clearing the TPM and setting up my pin number again solved my problem.

Per MS article 12/21/21 This same article strongly recommends when clearing the TPM that it be done from within Windows and not from within bios.

Clear all the keys from the TPM​

You can use the Windows Defender Security Center app to clear the TPM as a troubleshooting step, or as a final preparation before a clean installation of a new operating system. Preparing for a clean installation in this way helps ensure that the new operating system can fully deploy any TPM-based functionality that it includes, such as attestation. However, even if the TPM is not cleared before a new operating system is installed, most TPM functionality will probably work correctly.
