GPU Scaling missing. Questions + Workaround for Asus XG27AQDPG / RTX5000

I'm sure some of you will ask and yes, I went through multiple DDU runs with different driver versions and I did the entire CRU process etc, did not work.

Context: I recently switched to the Asus XG27AQDPG 1440P OLED 500Hz monitor and noticed I no longer had the GPU as a scaling option, only Display was shown. As I play CS2 with black bars this is a big issue as you need GPU scaling in order to make black bars work.
I've searched and read a lot of posts about GPU scaling option missing with dual monitors and from what I'm understand is, that this is still an on-going issue for many people.

Questions:
1-Will there ever be a fix from NVIDIA's side or has this to do with bandwidth limitations?
2-Is there a better known workaround than what I used?

Workaround: So what worked for me is by using the 9800X3D's iGPU for the 2nd monitor but this didn't work correctly right away so here's what I did to make it work.

Only install NVIDIA GPU related drivers, no need for Adrenalin as the default MS driver works good enough. I had to connect my monitors in a certain order for what ever reason so your mileage may vary.
I connected my main monitor to the GPU via DP port and the second monitor with HDMI to the motherboard and booted the PC. Next I unplugged the HDMI and set GPU scaling for the main monitor and rebooted the PC. Finally, I connected the HDMI again for the second monitor and now GPU scaling stayed activated for the main monitor.

Specs: 9800X3D/64gb/RTX 5090 with latest drivers.
Monitors: Main: Asus XG27AQDPG, Second: MSI Optix G273QPF(set to 1440p 60hz)
