edit: to hide status bar icons(may be version dependent):
1) `adb shell dumpsys activity service SystemUIService`
2) search for "icon slots: " and note down names
3) `adb shell settings put secure icon_blacklist battery,wifi,clock, ...` (blacklist is overwritten by new list upon running this command)
There's lot of undocumented things you can do with those, which the developers include because of their own itches. For example, i know most of the android and pixel core team at google have toggles for wifi and data. But they shipped a single quick setting tile for both. Yet there is a hidden setting to bring the two tile mode back.
