Can I plug an M2 to a PCIe Gen3X4 slot?

Can I plug an M2 to a PCIe Gen3X4 slot? m 2 slot with pcie x4 lanes Most of those cards are x16 and their switches split to x4x4x4x4 But there are x8 cards with 4 sockets which then split to x2x2x2x2 Check m2 expansion slot Typically, a or drive uses four PCIe lanes I would like to operate or drives with only one or two lanes per drive instead

m2 expansion slot NVMe SSD in socket X , using all four PCIe lanes WiFiBT in socket Y I am not sure if

m2 slot mainboard 2 SSD drives utilize up to four PCIe lanes With PCIe , they achieve almost 4,000MBs PCIe: Universal interface for many computer components  Default is using 4 lanes but SSD will also work in x2 mode But with slower data transfer speeds But do not be confused with PCI
