If I understand that comment correctly, it is for the example with
three servers, where two and two agree with one another, so that's a
different case, and the "arbitrary choice" is for selecting the system
peer, not a falseticker.

No, I don't think there is a non-source option that would force
chronyd to select a source in this case.
They should disable the bad server.
