Mainline today, for instance, doesn't have unaccepted memory support for TDX or SEV-SNP guests. But, they both still boot fine because folks either configure it on the host side not to *have* any unaccepted memory. Or, they just live with the small (4GB??) amount of pre-accepted memory, which is fine for testing things.
