Don't know if anyone is still interested but I installed a Samsung EVO Plus 500GB NVMe M.2 . I did some research here and there so I just disabled all SATAs and had zero issues being recognized when performing a clean Windows 11 install (Rufus patched ISO, downloaded directly from MS, via USB flash drive boot). I have a G20CB so my only issue is that the M.2 ran a bit warm at 70 degrees due to it's limited airflow design. I came up with an "Out of Box" ventilation cooling solution that has now brought down temps to average of 47 degrees, stable and quiet. I am considering trying a 1TB of the same to see if it will take (read at . I have latest BIOS installed. I then added a 4TB SATA by Crucial, upgraded RAM to Samsung 16GB x 2 for a total of 32GB and just ordered a new Mini PCI-E WiFi 6 + BlueTooth 5.0 combo card! Running real smooth and quick!
