Nvidia + Wayland. Headless Ultra-Wide Virtual Display?

Good Evening Linux Community.

I am struggling to find a solution (and perhaps my google-fu and search-fu are failing me).

I have a 5060Ti, and I want to use Bazzite, though I am not committed to this or any specific OS. I can happily use any Gnome / Cosmic based Distro and immutability is not a concern either.

Most of the Distro's are Wayland native supported.

On Windows - I am using Apollo (A Fork of Sunshine, that enables Virtual Displays)

My current gaming rig is completely headless. It sits on a desk, with no outputs. Just a power cord and ethernet.

I have a Mac mini which is connected to an Ultrawide (5120x1440), and use Moonshine to stream games from my headless gaming Rig to my Mac. This works perfectly under Windows.

On Linux, I cannot figure out a way to create a headless display so as to stream 5120x1440. I tried creating an EDID but I believe I ran into problems with Nvidia Drivers and fake EDIDs on Wayland not being supported (correct me if I am wrong!).

Apollo and Sunshine both say Linux support for Virtual Displays is coming, but that could be a day could be months.

I do have a dummy-hdmi I can plug in, but that maxes out at 3440x1440.

How, under Linux, can I achieve having a headless gaming PC, with a virtual display under Wayland with a Nvidia card to stream at my ultra wide resolution (5120x1440)?

Thanks to any and all who reply!
