m.2 help

[Hiyadragon]

Hello, first post from longtime lurker...

 

I purchased a laptop " Acer Aspire-E5-575G-52RJ " for my wife last year and wanted to do some upgrading of the RAM and 5600rpm HD with a ssd. Upon opening the laptop up i spot this next to the sodimm slots on the motherboard

I find a m.2 M-key slot there is nothing mentioning this on the acer website, amazon or newegg . I found a schematic for the Motherboard  https://imgur.com/Wug2AFX https://imgur.com/5qbPp1u It's " zaa x32 (zaaa)  "  If you look  it says there is a m.2 on a PCI-E 1x lane. What i am asking, is this a m.2 Nvme capable slot since it's in a PCI-E lane or just a m.2 slot?  

 

Thanks, Hiya
