How to let FPGA get access to HPS pins

I've got an Arrow SOCkit and it has a USB-UART connected to the HPS' pins, but I'd like to access the UART from the FPGA logic. Is this possible? If so how is it done? Thank you!

Hi, If I may interfere with the discussion... I'm using the DE0-Nano-SoC Kit, and would like to access both HPS CPS CAN1/2 peripherals. The convenient way looks like attaching my CAN PHY to the FPGA expansion pins. Therefore, I need to route the CAN TX/RX HPS pins to existing FPGA I/O. Can I choose which FPGA PIN with be used? Thank you 😊Ran
