WordPress supports only template files like single.php or content.php to be overridden. You can’t act in the same way with core functions and class files since it will break the structure of the theme its functionality.
We need to remove this line of code from Theme.php
Of course if we update each the theme we have to do that every single time (and your updates are often).
Sorry, but there are no other ways to disable this in our theme’s core. But we will remove the Redux framework one day completely and you will not need to do this.
