Unfortunately not. You'd need some kind of "maintenance" mode you could put a service in, where systemd would keep the socket open but just queues the requests until the service is put out of maintenance mode again. There is no such feature atm although I would have found that useful for Debian as well (during package upgrades). The best you can currently do is probably to stop the .socket to avoid accidental activation during the upgrade.
