Connect PM981 NVMe SSD with Jetson Nano SOM (without developer kit)

Hello,

Looking at the Jetson Nano SOM datasheet, it supports PCIe controller(Root complex) gen2. Is it possible to connect samsung PM981 NVMe SSD which supports Gen3.0?

Plan is to make a Base board with Jetson nano connected to M.2 key M (developer kit has M.2 key E) connector by routing PCIe interface, and connect SSD to M.2.
