Parece que usa AHCI não NVMe, se você usa o Google Plextor M6E M2 NVMe
este artigo com muitos detalhes:
Considering that, Plextor didn’t have to think long about what protocol to implement in its PCIe SSD product. To minimize potential incompatibilities, it is designed as a regular PCIe card and uses the AHCI protocol. Although not a very handy and progressive solution, it is guaranteed to work in nearly any computer that has at least one PCIe expansion slot.
Well, the actual product is rather more complex than that. Plextor unified its M6e with a similar PCIe drive designed for an M.2 slot. So the desktop M6e drive is an M.2 card (80x22 mm) mounted on a PCIe -> M.2 adapter. Thus, Plextor offers the M6e in two versions, for PCI Express and M.2 slots, which are in fact one and the same drive.
Se você olhar para este diagrama de A pilha de drivers do Linux IO mostra que os dispositivos NVMe são tratados de maneira bem diferente de outros dispositivos e aparecerão no sistema como /dev/nvme#n#
ao usar comandos como lsblk
