There is a feature known as NVMe namespaces but not sure how well it's supported outside of expensive enterprise gear https://unix.stackexchange.com/questions/5

  To a close approximation, NVMe devices that come in U.2 or U.3 form factors support multiple namespaces, and those that come in M.2 support only 1, and 4KiB LBA format support follows the same pattern with a few exceptions. But you don't have to spend an insane amount to get these features. The Micro 7x00 series costs ~$100/TB.

    Generally datacenter drives like Samsung PM9A3, Micron 7xxx, etc., that are available in M.2 and U.2 have the same features between the form factors. The maximum size and performance may differ between them, but this is likely a side effect of physical size for NAND chips and power envelope.
