I found one person same laptop his bios stated PCIe gen 4 but he also had a gen 3 ssd. I check my bios it says nothing about gen 4. I read this ryzen chip will support gen 4. I installed the latest bios for this laptop its the first thing I do when I setup a new machine so if it bricks the laptop I just return it. Asus web page for spec just states gen 3 ssd installed but not that it is not a gen 4 PCIe. Was hoping this is AMD latest and greatest CPU and GPU. I know its only ddr4 not ddr 5 memory not sure if that matters.
