It's a 16x slot, but it only provides 4 lanes of PCIe 3.0
Appears to be a SoC limitation, which only has a single 4x PCIe 3.0 interface, and doesn't appear to support bifurcation (splitting into two 2x slots, or four 4x slots). You could probably throw a PCIe switch on it, but PCIe switches are expensive.
The SoC wasn't designed for this product, it was designed by 3rd party company for computer vision/robotics/manufacturing use cases.
