It depends on what you want to do.

If you want NM to never touch your wired device, add:

NM_CONTROLLED="no"

to its config file.

If you want that device to just have a static IP, edit the config
file appropriately, and NM will handle that.

If you want to disable NM entirely, 'systemctl disable
NetworkManager.service'.
