Topton Ryzen 7840HS - Add PCI Device problems

[Merwenus]

First of all I'm a v1.0 user, I use online guides and youtube videos and google searches to setup things. I have no knowledge in Linux or in Proxmox at all!

I have bought a Topton N17 motherboard with 7840HS and I could easily install proxmox as a main OS and a DSM 7.2 inside.
I run into a problem and I really hope there is a solution for that without buying another board: The previous Topton board had Intel N6005 cpu and I could see almost every PCI device when I added as a Raw Device.
Sadly this new board is almost empty (beside ethernet and audio) and I can't passthrough the GPU or the Asmedia Sata controller (both device name missing). The bigger problem is that the iGPU has no IOMMU group in Raw Devices and when I add 00:00.2 iGPU and start the VM I get this error : cannot open iommu_group no such file or directory. When I added the 04:00.0 Asmedia device and started the VM the whole proxmox crashed and webui was not accessible the processzor run at 100%. HDMI output showed that filesystem became read only, and I couldn't even SSH into it.

I tried with a clean new install of Proxmox version 8.2.2, and with Post PVE install script and 8.2.4
In the bios I found IOMMU and tried with AUTO and ENABLED too, same thing:

I also tried update-pciids command to update names with no luck. Can someone point me in the a right direction if there is any solution with this stupid problem?

I guess there is on "simple" solution for this. :\
