M.2 SSD is not detected in the BIOS or by Windows 10

[CSG100]

I recently put together a system with an ASUS Z170-A motherboard and an ADATA SP900 m.2 Solid State Drive (Windows 10). The SSD drive is not detected by the windows installer, or the BIOS.

I have updated the BIOS to the current version, I have tried removing and putting back in the SSD, I have tried setting the boot control to UEFI and Legacy, and just UEFI, nothing seems to work. I installed Windows 10 to the hard drive instead, and made sure drivers were present for everything. There are no driver issues in the Device Manager. The SSD is still not detected

Does anyone have any suggestions?

There's a setting in BIOS "M.2 and SATA Express Mode Configuration".
Switch it to M2.
