BOIS does not see the M.2 2280 SSD, how can I find it?

Question

Solid State Drives

Good afternoon, who faced, help.
The essence of the problem: There is a WD Blue SSD 3D NAND M.2 WDS500G2B0B, the system does not see it, in the BIOS, when you select emptiness.
In addition to the SSD, there are no hard drives, although when I connect it, it detects hard drives.
I installed Windows on a hard one, in fact, the SSD is also not visible there. Tell me where to dig?
Motherboard: Gigabyte Z390 AORUS ULTRA.
BIOS updated to latest version: F7f.
The SSD itself is plugged into slot 3: M.2 (Socket 3, M key, size 2242/2260/2280) for connecting PCIe x4/x2 SSD drives; (M2P) (tried to stick in the second one, no change).

Answer 1

WDS500G2B0B is a SATA drive.
You plug it into a PCI-E slot.
It would be strange if it worked.
Well, you yourself say

for connecting PCIe x4/x2 SSD drives

and nevertheless stick a SATA disk into it. What else should be the result?
