Hi Albert,

Thanks for the reply. I will try it later.

I also did some work around, I manage to run the raspberry pi4B with chromium os with KIOSK mode.

Not sure you interested on it or not. It works quite well except it dont work with PI3/PI3B/PI3B+ as the developer still not resolve the chromium os version on R89 to support PI3 group.

The only issue of this KIOSK mode is it dont support USB only.
