Context
TDX attestation verifies the TDX module using various versions and hashes.
One optional value for user validation is
MRSEAM, the "measurement of the Intel TDX module. (48 Bytes hash)".Setting this value ensures attestation only passes if the CVM is running with an Intel TDX module which matches this exact hash.
While this blocks older versions of the module from running (this is also prevented by other versions checks), it also effectively blocks using newer versions.
