Elegoo 3.5Inch Display-Shield on RockPI 3C

I currently doing my first steps to replace my Raspberry 3B with ROCK 3c. As I have several 3.5 inch touch-displays from Elegoo here (https://www.elegoo.com/products/elegoo-3-5-inch-tft-lcd-screen) I’d like to get them running on Rock 3c.

For Raspberry there is a nice documentation at http://www.lcdwiki.com/3.5inch_RPi_Display but I have no clue how to get this setup on Rock 3c. I already tried to find the matching locations and configurations but right now without any success.

Any hint on getting those displays running would be highly appreciated.

Best regards
Jens
