Acquiring an image from an m.2 (nvme?) drive that had been running Linux

My Windows-based PC doesn't detect it at all, and it's not detected through Autopsy, Axiom, or FTK Imager. It's just a little 128gb SSD (m.2 form factor- two notches). It's connected to a write blocke external pcie port.

Any advice? First time trying to do a Linux drive.
