ModemManager can optionally use PolicyKit to ensure non-root users
can't mess up the modem.  If you don't care about that, or you have a
single-user system, or an embedded-type system, you may not want to use
PolicyKit at all.

You can disable PolicyKit at build-time by passing the "--with-
polkit=no" option to the configure script.
