Hello! Need help please. I have an Asrock b450m steel legend paired with ryzen 5 5600g. I installed a new Samsung 970 EvoPlus 1Tb nvme in the Ultra M2 slot but it is not detected even in BIOS. I've read on some post to look for the "Force M2_2 to support PCIE devices" but I cannot find that setting anywhere in BIOS. I already updated my BIOS to the latest Beta version P10.43.
