flip cover Help, please!!

Hello, my problem is this:
I have to protect my Galaxy S6 Original flip cover from Samsung.
The screen turns on and off by itself when you open or close the flip cover.
(this is correct).
But I want to disable this function in my galaxy s6.
It's posible?
I have a Galaxy s6 32gb .
With firmware G920FXXU2COH2 base.
not root (for the moment).
