For Galileo they have something where basically each message contain something to authenticate the previous one. So this could be fully based on ground segment. Anyway, they have probably countless reasons to update software anyway considering the many services that were added after their launches years ago.
What GNSS satellites do is (approximately) timestamp a message they receive from ground. They don’t really know their position by themselves, they are clocks in orbit.
Galileo has something like that, I don’t know if it’s deployed yet
Btw, software updates are a thing for satellites, but I’m not sure it would be needed for this, it can probably be done on the message sent from ground to the gnss constellation
