I honestly don't know.

What we actually need is the TDX module version. I'm not sure how
tightly tied the TDX module is to the BIOS version. I suspect that
they're actually completely independent.

Once we have the specific TDX module version, we can go ask the folks
who write it if there were any RBP clobbering bugs.
