Unfortunately, I think you’re going to run into trouble because fido authenticators are geared towards working as user authenticators rather than as device authenticators.
It certainly should be possible from a technical perspective, but implementation-wise, it’s very likely that the code focuses on making fido devices work with client keys, and using tpms for host keys, since that’s much more focused on headless server functionality.
