how to configure and use both wifi and lan with OMV on Raspberry PI

I have OMV running on raspberry pi and connected through LAN - everything is fine.

To configure a wire-guard tunnel, using WIFI instead of LAN, when I try to add WIFI to the list of interfaces using OMV UI (network > interfaces), even LAN gets disconnected and I have to run omv-Firstaid from physical console to re-configure LAN. Is there a way to enable and configure both LAN + WIFI through OMV.

I have seen options to setup both WIFI and LAN through ssh and manually modifying files, but everything is messed up by OMV on reboots or after updates.

Got it. So, good to know that I can use both adapters for network aggregation only. I will think about bonding them later.

But the first issue is that when I add wlan0 through OMV UI (network > interfaces) and reboot the server. LAN (appearing as end0) disappears from the network interfaces list and I lose connectivity through it.
