No Usable SPI Port on Pixhawk v2 (The Cube)


I’m a beginner to the Pixhawk/PX4 scene and I had a sensor configuration question that I cannot seem to find an answer to elsewhere online. I’ve purchased the Pixhawk v2 (The Cube) and wanted to relay information from a Teensy 3.6 microcontroller to the Pixhawk. As it is accelerometer data that I will be relaying, I’d like to use SPI over I2C. I see in various documentation that the Pixhawk v2 has SPI capabilities, but it doesn’t seem like its usable, at least compared to the labeled SPI port on the Pixhawk v1. Is there a way to make an SPI port on the v2 like the v1 has?
