T2080RDB-PC GPIO Access

I'm working on a T2080RDB-PC development kit, and I need to access GPIO such that I can use an external piece of hardware to trigger interrupts in my software running on the processor. I've looked over the schematics, and I cannot find any GPIO pins that are accessible on the board. Does anyone know if I'm missing anything, or if there is a way to get to GPIO on this platform that I am overlooking?

On T2080RDB board there are no GPIO signals connected to a header directly.

Some ways to let GPIO to use (after muxing in RCW):
1. DUART 4 pins to GPIO, we have 4 pins to use as GPIO on header J35.

2. SHDC/SPI pins to GPIO, but it requires connect lines on board.
