Use a check_recipient_access restriction and put
reject_unverified_sender in the right-hand side for the recipient
domains for which you want to perform SAV.

main.cf:
smtpd_recipient_restrictions =
        ...
        check_recipient_access hash:/path/to/file
        ...

/path/to/file:
example.com reject_unverified_sender
