GPIO for Neousys Technology Inc. POC-200 Series

[Janbo]

Hey im trying to run RpiEasy on this small embedded PC which has several different input outputs includion GPIO's General Purpose Input Output pins.
I have Debian 11 installed and the Rpi Easy server runs fine but it ofc doesnt recognize the GPIO's how would i go about to map the pins to the GPIO's ?
Where would i have to change it ect ? or is that not possible ?
