How to change avast settings in safe mode ?

I want to change settings not to start after boot for Avast or disable raw disk access for example, but can’t change ANY value . It is resetting after close. Where the Avast .INI file is located ???

The service is not running in safe mode, so changes to the settings don’t get saved.
Raw disk access affects the boot-time scanner only, so there’s no point in changing it in safe mode. What exactly are you trying to achieve?
What operating system do you use?
