That is indeed quite unusual. Please check if you have the service 
"NetworkManager" running. It *should* be running on a 5210R and it will 
keep the network settings applied.

You can check it this way:

[root at 5210r 5210R]# systemctl status NetworkManager
● NetworkManager.service - Network Manager
    Loaded: loaded (/usr/lib/systemd/system/NetworkManager.service; 
enabled; vendor preset: enabled)
    Active: active (running) since Tue 2021-12-21 23:19:47 -05; 1 months 
15 days ago
      Docs: man:NetworkManager(8)
  Main PID: 32301 (NetworkManager)
     Tasks: 3 (limit: 49500)
    Memory: 6.2M
    CGroup: /system.slice/NetworkManager.service
            └─32301 /usr/sbin/NetworkManager --no-daemon

It should say "Active: active (running)" and also above it should 
mention "enabled".

Older versions of BlueOnyx had NetworkManager disabled, but since it 
became an integral part of EL8's network configuration all the GUI's 
network scripts now make use of it to apply the configuration. If 
NetworkManager is disabled on a 5210R, then you might see the effects 
you're now experiencing: Loss of network connectivity after a reboot.
