First, do a

  systemctl stop NetworkManager.service
  systemctl mask NetworkManager.service

Get well informed about the mask command in "man systemctl".

Then, configure properly the wired network interface to use the old
network service (most notably, pay attention to "NM_CONTROLLED" keyword
in /etc/sysconfig/network-scripts/ifcfg-<yourwiredinterface>).

Finally, when everything is set up properly, do a

  systemctl enable network.service
  systemctl restart network.service

or do a "start" instead of "restart" if it is not active already.

What do you mean by "entirely"? How exactly did you disable it?

All apps should work, regardless of NM or network.service being active,
as long as everything is configured so that the latter two don't clash
into each other. If Xorg or other things crash, it's a separate issue.
For one thing, Xorg should be operational for an offline machine as
well as an online one (although maybe it requires the loopback
interface to be active, I'm not sure).

Make sure that NM is masked and network.service is correctly configured
and operational. After that, report separately any issues that you might
have with other apps.

HTH, :-)
