To anyone that can help:

I have a HP envy x360 M6-W105DX convertible laptop.

It has an M.2 slot compatible with an 256GB SATA TLC M.2 SSD (manual linked below)

To that end i purchased a Samsung EVO 860 SATA 250GB V-NAND SSD (linked below) and installed it into the slot.

The Problem: The SSD is not being detected anywhere, not in bios, diskpart, disk manager, windows explorer, device manager or windows installation media even when i disconnect the primary HDD.

Does anyone know why this would be?

From what i can gather, HP disable the M.2 port at the factory unless a M.2 SSD is factory installed and they then lock and hide advanced settings in BIOS so that i cannot turn the port back on. Do you agree that this is what they did?

My only course of action is the reflash the BIOS CMOS with an open BIOS that gives me access to the advanced settings so i can turn on the port. Do you think this is the way to go? i have never flashed a bios before and i am hesitant as it can brick my laptop of which i cant really afford to replace.

Solution
There is a good chance that HP disables that port and no reason to believe a BIOS change will enable it. The board supports SATA 3 so I would swap the M2 EVO for the 2.5 version which will be just as fast and not risk whatever damage changing BIOS might inflict.
