I never use network manager but just in case it's of use, check
out /usr/share/dbus-1/system-services

Stupid place I know (not a Ubuntu decision) and documented very poorly
in the man pages but you can mv the network manager files out (I use an
off folder within) or by also moving the polkit files, be pretty
confident that the machine will only allow as root what you OK in
sudoers with added security for many reasons or with suid execs.

You can have a boot script to ask whether to move them in and out for
different locations.

p.s. I think Ubuntu shipping sudoers files with lines that can be easily
enabled (if following the authors wishes of secure by default) or
disabled with # and enabled by default for Ubuntus goals of usable
by default would be a far more easily and centrally managed ,intuitve
and controlled system than the current one not to mention more secure
in many ways including showing users they can lock down their
desktops beyond ALL:ALL.
