Hi Elina,
I'm Sumit, here to answer your query at the Microsoft Community.
Apologies for any inconvenience you are experiencing. We are happy to help you.
If the drivers have not worked, we can try disabling VMD in BIOS. It shows up the drives.
Shut down your PC completely.
Power it on and immediately start pressing the Del or F2 key repeatedly as the PC starts up.
Continue pressing the key until the BIOS/UEFI menu appears.
Look for Storage options and toggle the VMD option.
Hope that helps, and rely on us for any further inquiries. All the best.
