There is no option to do that. You would need to write a script
checking the reachability and calling chronyc allow or deny as
needed.

A server which lost its upstream sources is not considered
unsynchronized in NTP. Its root dispersion should be increasing and
it's up to the clients to decide if that is acceptable.
