AMDGPU(0): [drm] Failed to open DRM device for pci:0000:03:00.0: No such file or directory

When i'm booted into NixOS stable i can confirm it is the right PCI BusID.

[root@gaming:~]# lspci
...
03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Navi 23 [Radeon RX 6600/6600 XT/6600M] (rev c1)

So it's not the issue that is does not find the GPU or use the wrong (i have only 1, not even integrated).

Could you share modinfo amdgpu, uname -a, and dmesg here for reference? I'd like to make sure it's actually loading the dkms amdgpu module, but I'm not 100% sure how to verify that. It'll be a few days before I can test it myself to compare.
