Dell's specifications state that it supports PCIe NVMe 3x4. Note that Crucial does not say that the laptop supports Gen 4, only that you can use either Gen 3 or Gen 4 drives in it. However, a Gen 4 drive will run at Gen 3 speeds. Whenever touching components or working inside a computer, wear a grounded wrist strap, also called anti-static wrist strap, ESD wrist strap, or ground bracelet. It's a cheap and sensible precaution. Rest the laptop on an anti-static mat or at least a reasonable alternative such as corrugated cardboard. (Repeatedly touching a metal case part is not sufficient mitigation with modern components.)
Hey What gen nvme is the latitude 3510 compatible with? Read some dell documentation that says gen 3 and some sights like Crucial state gen 4.
