M.2 key M slot of the latte Alpha , western digital black 1To NVMe SSD not recognised by windows

I instaled a western digital black 1To NVMe SSD in the M.2 key M slot, not recognised by windows, Only the drive C with the system is detected. Is this card suported? Is the slot defective ?or something to modify in the bios or additional program to install ? Could you list some precise références of cards that will work for sure on the alpha.
Many thanks for some help
