I actually have the 15 inch version of this same laptop which has essentially the same motherboard. On yours, there are two M.2 SSD slots (and 4 memory slots) and then also a pair of 2.5 inch drive bays (the 15 inch only has one 2.5 drive bay). And yes it accepts PCIe/NVME M.2 SSD. I use one of those for my boot/system drive then have a large SATA M.2 in the secondary slot and a large SATA 2.5 inch SSD in the 2.5 bay. You have virtually endless storage options in that machine in other words.
Post back if you need any more help and please accept as solution if this is the info you needed.
The second slot - there is only room for a small m2 drive - I have an m2 sata drive, which was the original drive which is too long to fit in the space.
I've attached a photo.
Can I still install the sata m2 drive? (its the same length as the NVME drive) How would I hold it in place? I could use the cable from the battery to hold it down, risky maybe but the laptop doesn't get moved about much.
