How to check what kind of connectors I have on my laptop for drives

I'm wondering what kind of SSD to buy under the M2 for the Acer f5-573G-50SK and here comes the first question what kind of connector I have, how to check, but one thing I'm rather sure of is that it does not support NVME, but the question is whether it supports SATA 3 or maybe PCI-Express? Would you recommend some software to check this? And the best possible M2 SSD drive? My guess is the XPG-6200 or 8200 pro, on PCI-Express of course, but I'm waiting for an answer.

Just look at the specs.

I would advise you to check it by SNID number in your query to Acer technical support.
You can also look at the M.2 connector on the board, I think the B+M key.
