Supermicro X9 question (bios mod for TPM2.0)

Hi everyone,

I've seen a few BIOS modifications floating around for the X9 boards (NVMe boot) and wondered if anyone has attempted updating the TPM support in the X9 BIOS to support TPM2.0. According to Supermicro you need X10 or later to use the newer TPM chip, and plugging the newer model in results in the "SUPPORT TURNED OFF" message. I'm not sure if the v2 Xeon's are compatible with the later TPM (they do support TXT though) or if the DXE's could be ported from an X10 BIOS, but figured it was worth asking around before heading into mmtool/uefitool.

Thanks!

Just updating here for future reference, from looking at some of the technical manuals from other vendors it appears that the v2 Xeons don't support TPM2.0, you need v3 or later (so no BIOS mod would fix this sadly).
