In latptops/workstations NetworkManager takes care of everything. However,
I still enable systemd-networkd and systemd-resolved in my laptop and
workstations. If enabled without any configuration, it just monitors the
network interfaces and keeps them "in the loop" for the rest of the system
to know about them from a central registry. It doesn't interfere with
NetworkManager (or any other network management program for that matter).

It's not mandatory to enable them either. However, there were advantages to
doing so; for example, in my laptop, systemd-timesyncd would try to sync
the clock only if there was a network connection available.
