I have a B550-F gaming (non wifi), and there isn't a TPM header.
No stuttering problems since a BIOS upgrade was released to fix that problem.
By the way, BIOS 3002 is now available, upgraded today and no problems to report so far.
I wonder if the problem you are facing is indeed a problem with the TPM, can you provide more details?
Perhaps is something else that we can help you with
