USB-3 and PCIe solution to use both

I am using the Khadas Vim3 for a project I am working on. One thing I want to do is record camera pictures over USB-3, and save them over PCIe on an SSD card plugged into the in the M.2. slot.
In case I use the SSD card the USB-3 is switched to an USB-2 which limites the framerate of my camera.
(see here: PCIe/USB3.0 Port | Khadas Documentation)

Is there any solution to circumvent that? I thought of something like a hub which can be plugged into the M.2. slot and has an USB-3 and an other M.2. slot for an SSD card.
Thanks for any suggestions.
