What m.2 ssd can I install in this socket? Asus zenbook ux510uw

This is the socket. I want to install a m2.ssd its a Asus zenbook ux510uw. I’ve been reading and came to the conclusion that I can only put an m.2 SATA ssd (which is fine) however when I opened the laptop I saw that the port has only 1 hole

like the one on the left in the picture, and the ssd I wanted to buy has 2 holes like the one on the right. And most nvmes have only 1 hole(left) and SATA ones(right) have 2 .

So my question is what can i put it the slot in first picture Sata with 2 holes? or nvme with 1 hole?
