@ethan.hsieh @ivan.hu,

Response from our BIOS/TPM Engineers:

"Hash Algorithm Bitmap  is set in BIOS and it’s based on build
configuration PCD and active PCR’s supported."

This BIOS is also distributed as reference BIOS for IBVs and hence
disabling SM3 would break functionality on other Platforms/BIOS

The way to go would be to enable SM3 on go-tpm2 and tpm2-tss tools, I see your 
request to enable SM3 in go-tpm2/secboot here:
