At this time, you either remove the modem-manager package, or you remove
the dbus auto-activation file referenced earlier in this thread.

I have various ideas how to only run ModemManager on-demand, which
basically revolve around using udev to spawn ModemManager if it's not
already running when a new serial port appears, and have MM quit if it's
not managing any modems.  NM would then stop poking MM automatically,
and just rely on its presence.

The one thing that doesn't solve is if MM crashes, it wouldn't
necessarily get restarted automatically, which is quite useful to
recover from bugs for users that don't know how to manually restart it.
