[Q] Expanded desktop/Immersive mode from shell/shortcut topic

I know that the secure settings app can gain access to expanded desktop,

i want to integrate expanded desktop for root users on CM/PA etc with expanded desktop/immersive mode on thier device and trigger it during specific scenarios. is there anyway to toggle using shell (i.e. force set to on or off)

ive been looking at implementing something similar on non-rooted devices so not having any luck atm, so i thought i would start with root users and devices without navbar
