How to install an M.2 NVMe SSD in an OWC Express 1M2 enclosure 

We see no reason why the software would not work as long as the enclosure was holding a Samsung drive, however, we recommend looking into the full compatibility with that program and the Apple Silicon Mac.

@@poweredbyowc Thanks for your answer! Yeah, Samsung Magician's functionality is limited on Apple Silicon Macs in comparison to Windows. Still, will the NVME M.2 SSD connected via the OWC Express 1M2 enclosure be treated by the Apple Silicon Mac as an internal or external drive?

It will still be treated as an external drive.

Yes, it works.
