The NVMe on the VIM3 is at the USB3 speed. 

Have you checked? ;-)
Looks like...the board may have the higher speed for NVMe then USB3.0

Amlogic A311D

Integrated I/O Controllers and Interfaces
• One USB SS and PCIe 2.0 combo interface up to 5Gbps, supporting 2 configurations:
o 1 USB 2.0 Host + 1 PCIe
o 1 USB3.0 (No PCIe)

Diff switch:

FUSB340: USB 3.1 SuperSpeed Data Switch, 10 Gbps

And the second intresting point.
NVMe may "fix" the problem "Wifi issue with USB3/No 5Ghz wifi. Could have solved the USB3 interference"

Hi,

Could you check NVMe speed for Khadas VIM3, please?
I guess it`s possible to connect NVMe SSD direct to the board without Khadas M2X Extension Board.
Thank you.
