Extend PCIe1x1(GEN3) of Xavier NX to 2-port USB3.1 using USB XCHI controller

Jetson Xavier NX only has 1 USB3.1 port, but I need 2 or more USB3.1. Xavier NX has a PCIe1x1 (GEN3). Can I use the USB XCHI controller to expand more USB3.1 ports?
For example,VL806 (PCIe GEN2), ASM3042 (GEN3). Can you give me some advice on this?

There is only one USB3 root hub in Xavier NX module. So for having more USB root hub, you would need to have USB host controller to convert PCIe to USB.
