Clear TPM using CCTK w/ no presence at PC

Using the latest version of the CCTK 3.0.0.1, I need a way to clear the TPM using the CCTK.

--tpmppidpo & --tpmppipo are available, but the description for them is very vague and there's hardly anything useful in the manuals about them. I've tried various combinations of these and can't seem to make any progress w/ it.

--tpmppidpo: Enables or disables physical presence for the ACPI TPM PPI deprovision operations.

--tpmppidpo: Enables or disables physical presence for the ACPI TPM PPI provision operations.

I need to be able to clear the TPM during a OS refresh without the need for a user to be at the PC to press F12 to clear the TPM.

It is possible to clear TPM only through BIOS screen due to security restrictions.
