Yes, there will be a single binary supporting both tdx and non-tdx, some
configs add sev to the mix.  Doing the same for cloudhv shouldn't be much
of a problem I think.

In tdx mode the firmware uses the tdhob for memory detection, in non-tdx
mode qemu fw_cfg is used instead.  The cloudhv build could switch
between tdhob and pvhinfo in a simliar way.

take care,
 Gerd
