Why not install proxmox on the bare metal of the NUC, then add VMs and containers inside of Proxmox for your reverse proxy, blocky, and other services? Maybe this is what you are doing and I just don’t understand.

I have Proxmox installed on bare metal in my primary home lab server. I also run a Synology NAS on the side. I’m not running Synology Drive for any clients, but I’ve set it up for others before, and it works great in this configuration.
