I have seen ways of adjusting the adaptive refresh rate but not the method you highlight @AMRKHN
To be honest i can't really tell much difference between the two display options but I can tell the difference between refresh rates.
Adding or changing what you highlight I'm sure would have an impact on battery life. How much would have to be experienced to see.
