Needs to replace I2C touch screen driver, tried different ways (UEFITool, Fiano, H2OEZE, inserting second driver, replace original) but machine doesn’t boot. It’s all from BootGuard? Any chances to replace it?

here if it doesn’t work then they are implanting RSA signature or similiar or it just the new driver doesn’t compatible/work.
