[SOLVED] Is any BIOS configuration needed after installing an M.2 SSD?

Solution
Only requirement is not to use sata ports SATA5 and SATA6.
Those will be disabled, when using M.2 device.

Make sure SN750 is being properly detected in BIOS.
SN750 uses PCIE x4 operation mode. So if BIOS has option to set M.2 slot mode, then set it accordingly.
