Windows VM Sees Display Console as a Connected Display

Hello all,

I am passing through a GPU to Windows 11 Pro VM. The GPU has an HDMI dummy plug on it for gaming remotely via Moonlight/Sunshine. I would like to be able to use the Proxmox web GUI for managing the VM, but Windows sees the console display as connected display. I'm sure this is probably normal behavior, but I am wondering if it there is a configuration that will allow me to use the Display Console and have it show the same display as the dummy plug display. Setting them to duplicate inside of Windows does not work as Moonlight will no longer connect. Currently, the Display Console is the primary display in Windows and games won't run that way. If I set the dummy plug as the primary display, the settings in Windows gets stuck on the Display console and other weird stuff happens. I can only move the mouse between the two screens if the Display Console is full screen.

I would like to have Windows see only the GPU connected dummy plug, but still see the VM in the Proxmox GUI when Moonlight is not connected. Is this achievable or do I need to install something like VNC viewer?
