I think not. Well, you can call `nmcli connection down` from a
dispatcher script. But then activation already stated. Also, it will
block future autoconnect.

If you have a more complex policy about autoconnect, I think that you
would disable "connection.autoconnect" in the profile, and let your
scripts/tool handle the activation.

It seems what you ask for, is a more elaborate policy about how
profiles can autoconnect, and moreover, how they conflict. That would
be an interesting feature, but relatively hard to design correctly.
