Dsi screen breaks i2c devices

Im using the rock 3a board with a waveshare 4.3 DSI screen, (https://www.waveshare.com/wiki/4.3inch_DSI_LCD) this works fine once I added


to the uEnv.txt file.

however I cant see any other i2c devices that are connected. If I remove the overlay and add


then I can see my other connected devices but the screen no longer works. enabling both does not solve the issue.
I have seen hints that I need to disable the touch capabilities of the screen, but not sure how this is done? (I don’t need the touch for this project)

can anyone give a quick hint in if this can be fixed?

Many thanks
