Automated install still adds dtoverlay when using DSI display based setup

Hello,

I ran into some little trouble while finalizing the automated installation scripts (config.txt):

The automated config.txt shall contain no dtoverlay for the video driver, as I am using a DSI display which doesn’t need any specific driver (DFRobot).

All modified scripts for automated installation are running well and installation is applied as expected, except that somehow it will still add a “dtoverlay=vc4-kms-v3d,noaudio” after completion of the installation, which will lead to the DSI display to not function properly.

Is there some part where we can ensure that the automated “config.txt” won’t get modified in any part of the installation process?

Thank you, and keep up the fantastic work!

Lawrence
