Proxmox pass trough bios configuration

Hey guys, I am looking for a help to be able to use pass trough option for my VMs. I had everything working perfect before until one of my SDD failed (not proxmox) and in the process of troubleshooting we had to reset bios settings and to replace SSD. Unfortunatelly I did not save bios settings so I had to configure it again but for some reason it is not working. I followed proxmox instructions how to set up bios enabling some stuff but it still does not work while VMs work fine. My proxmox can be accessed trough web browser and my VMs are intact and I can run them on console but not pass trough.

My motherboard is Gigabyte Z490 Gaming X. It has onboard GPU and I also use 5500XT GPU.
If my monitor is connected to internal GPU I dont see bios while booting but I can see proxmox loading until log in. If my monitor is connected to an external GPU I can see bios loading and then it goes blank. If I run VM pass trough enabled I see blank screen.

Help would be much appreciated.
