How to permanently set one handed mode on Android or shift screen size?

My Xiaomi Redmi 4 prime’s display has broken from left side. So I have to use one handed mode which is miui’s default feature. Is there any way I can Shift my phone’s display to 4 inches from right side? My phone is rooted and Magics installed. Also I it has a custom recovery (OrangeFox)
