Don't run systemctl disable NetworkManager. You need to mask the
service to ensure interdependent services are not starting it up for
you behind you back. i.e. systemctl mask NetworkManager
Also, when you start it ensure it is set to start on boot. e.g.
systemctl enable --now network
Finally, heed the advice in the log. this is going away. I've had very
few issues with NetworkManager since ~7.4 onward and would suggest
giving it a go. I find it much easier to work with in scripts.
