I am making a LCD dashboard using this 1920x720 Screen with touch
Using a Radxa Rock 5b+ as the brain.

My question is, I do not want the HDMI2 1920x720@60Hz text at the top right which appears for every start of the screen. also it has a No Signal when there is no display in the screen ( this i can tackle by cutting the power of Backlight when there is no power in Radxa.

The Manufacturer has given me the .bin file which is the firmware for this. How can i edit and then compile it back without bricking the device. How should i solve this ?

Thanks in Advance
