[GL752VW Bought in SouthAmerica] Adding an M2 SSD, PCIe or SATA III?

[setszawa_r]

Hi, first of all I know the issue about the compatibility of the GL752VW's motherboard have been discussed vastly, but my problem is particularly special. I bought my notebook in Peru, and nor the regional Asus page neither the laptop itself has any indication if I need to buy an M2 PCIe or a M2 Satta III for my laptop. Does anyone knows how could I figure this out? The seller seems to be more confused than myself and I don't have the money to buy both types of M2 SSDs to test them. Thanks to whoever can give me a hint to solve this.

This is what it says on the Asus product page;

Storage - 1TB HDD 5400 RPM
1TB HDD 7200 RPM
2TB HDD 5400 *
128GB SSD (M.2 2280)SATA3
256GB SSD (M.2 2280)SATA3
128GB 5400 SSD (M.2 2280)PCIE x 4
256GB SSD (M.2 2280)PCIE x 4
1TB 5400 SSH

So, based on that, we assume it supports both NVME and SATA3 m.2 drives.
