Server running Debian Bullseye with KDE Plasma - I want to give OMV6 a go but would prefer not to remove plasma - Is this possible?

Hi All, I am new hear - I have been trying to search for information on this around the place with no luck - I haven't gone far enough to read through every single bit of documentation because that is a massive time investment for something that searches have yet to provide information on and may not be mentioned because it is not possible (right now?).

I have a headless server (most of the time - I can plug a monitor and keyboard into it if I have boot errors), that is running Debian Bullseye with DKE Plasma. I typically remote in from my main windows machine to terminal or to KDE Plasma when I have something I need to do or want to play around with Linux (which I am still very knew to).

I am in the process of upgrading from a 5 disk Raid 6 (5x3TB) setup using mdadm to a setup (most likely using ZFS probably zraid2?) using 6 x 8TB NAS drives. I have the System running off a 250GB SSD

I recently discovered OMV and am really interested in giving it a go, on bullseye I would be running OMV6 and would be installing this on top of the existing Debian system.

I know the recommendations say you shouldn't have a GUI desktop environment running, however I really want to keep KDE Plasma because I use it to play around in Linux from time to time and to do certain tasks that are just easier for me there than in terminal.

Can I install OMV6 and have it run and be accessible while KDE Plasma is installed? What would be the best way to go about this?

Thanks in advance for your help. System is based on on an old i7 2600K build.

Thanks in advance for your help!
