Hello,

No, some NVME SSD had a built-in "Option ROM" to make them usable as "legacy boot devices" in (some) systems that did not have native support for them but they are now uncommon, some adapters allowed the same to be achieved. Your system was not designed to boot from a pure NVME drive so its "bios" lacks the necessary code and it's so dated that no one (reasonable) thought to implement it at a later time.

In rather general terms, hardware aimed at the enterprise market is designed for use in those specific contexts, where anything that can compromise its reliability or complicate its supportability always translates into potentially economically significant damage.

Regards,
Ferdinando
