As I have not ever used NootRx, I don't know, but if your last EFI is what you're using now -- and based on the comments from
@Edhawk -- looks like you have to remove "agdpmod=pikera" from NVRAM. Also, I don't understand why your Processor is listing "3,18 GHz" in the above screen shot... the Restrict Events boot-arg from my/your EFI had the flag to correct that, so not sure what's going on there. You can try to remove both boot arguments for Restrict Events for now and see if that changes anything, but maybe you need to double-check your BIOS settings, most importantly, that your BIOS doesn't have iGPU active.
