I personally doubt that that might happen.
NethServer7 is CentOS7 under the hood, and it does not reconfigure itself unless root (or configuration deployment) “tells” it to do.
Then.
I’d suggest you as first step to see which version of kernel are you using (uname -r) then look for troubleshooting on internet about RTL8125 and your kernel version.
I had problems with Realtek newtork cards and CentOS 7, were 1gbs NICs; I described how I solved here.
Some other people suggested to use ElRepo instead of others solutions, but your mileage may vary.
Consider that if you installed manually a driver… the thing has to be repeated at every kernel update. So maybe an automated solution might be a better path.
