MNT Reform Next: External GPU OCuLink port customization?

I’m truly interested in combining an external GPU with the RK3588 module of MNT Reform Next. Two of the official documents hinted about this customization:

“break out the x4 M.2 connector to something like Oculink and drive an external GPU.”

“you can customize this board while making use of the available space under/behind the keyboard to add external ports, like external antenna connectors, or back-facing USB.”

I found some NVMe to OCuLink cable on Amazon or Alibaba and planned to 3D print a replacement backboard with OCuLink port and holder, but after a second look at the picture, it looks like there is a vertical PCB antenna blocking the backboard. Placing the OCuLink port on top of the MicroSD port on the left is also a choice if there is enough space.

I wonder how difficult it would be to customize the backboard with a PCB antenna. And is there anybody else who also wants a Reform Next with an external GPU?
