PCIe devices are required to boot up using x1 lane only, and then negotiate further lanes with upstream.

AFAIK it shouldn't matter if they're direct to CPU or not, at least not logically.

I note the drive is Gen5 capable, does it negotiate x2 5.0 lanes or something else?

Negotiates to 2x 5.0 so long as the board it's plugged into supports it. 2x 4.0 or 3.0 otherwise. Hadn't tested even lower.
