Adding an additional SSD to Omen Gaming Desktop

[cgi89]

I purchased an Omen gaming desktop this past week at Best Buy. According the expansion specs, it lists two 3.5" Bays,  three M.2 Slots, three  PCI-E x4 Slots, and one PCI-E x16 Slots.

It is my understanding that I should be able to add an M.2 NVME SSD. However, upon opening up my PC, I was unable to locate the additional M.2 slots on the motherboard. Are they behind the included SSD? I don't know; there is no schematic for this motherboard according to the HP support agent I chatted with today, and the "Upgrading and Servicing Guide" has no text besides just photos on basic how to replace the existing SSD and an "or" option that I'm not seeing on my motherboard. I am seeing the #4 NVME M.2 SSD with a cushion between itself and the motherboard screwed on so I'm confused where the other two M.2 slots are.

Any help would be appreciated.

I actually just saw on the Best Buy customer reviews that the 2nd nvme slot is hidden behind the gpu. It’s literally labeled “2nd ssd”. The third is the Wifi module. There was no information on the location of it anywhere on HP's support. Lack of schematic here is the reason for it.
