Technically, a Frum owner can be a Mashgiach for anything but the Minhag is not to let them. A Masshgiach is a type of Eid, but there are separate rules for that type of Eidus. It could be that someone who is Passul L’eidus is Kasher for this (there are a lot of different opinions and it depends on why he is Passul L’eidus). Each Va’ad will have to Pasken who they let be Mashgichim and who they don’t.
