Question Asus gaming z790 plus not recognizing one m2

Asus gaming z790 plus
Is this;
your motherboard? If so, what BIOS version are you on for said motherboard at this moment of time?

Make and model of the drives you're working with? If this motherboard is an upgrade over a previous model, did you reinstall the OS?

When in windows only 3 show up. I have done multiple scans to no avail
Did you look for the missing drive in Disk Management and Device Manager?
