PieFed has the ability for a moderator to restrict votes for all posts within a community to just members, not on a per-post level. Not sure if this is what OP wants.
Also, it is really more of just rejecting and not federating out votes from non-community members. The votes from people on remote lemmy servers would still be counted just on those servers. Federation across servers and software is weird that way sometimes.
I think Piefed has that feature.
