Does PYNQ Arduino Module support SPI via onboard Arduino header?

Board: PYNQ Z2 with latest pynq package GitHub - Xilinx/PYNQ: Python Productivity for ZYNQ.
In the, it says from the link about pynq.lib.arduino.arduino_io Module
: This class controls the Arduino IO pins as inputs or outputs. By going through the whole documents, it seems it only supports input&output with "0"or “1”.
What if I would like to use the SPI to communicate with the offboard devices via Arduino headers? Is there any suggestions?
The purpose is to read time serial data via the SPI channel for processing. Using PS IO can be an option. But I would like to know if pynq package can support that ,maybe in the future?
Many thanks.
