Comment #6 is the correct solution. On desktop images we want NM to manage everything, thus the installer creates /etc/NetworkManager/conf.d/10-globally-managed-devices.conf. But on a server, container, or similar environment we do NOT want NM to suddenly take over existing connections from netplan, networkd, or ifupdown -- there it should be restricted to wifi and 3G.
