Na bro it does not work. I have tried it many times.Install XDA's Navigation Gestures App (Available on Playstore)
connect phone to PC
Turn on USB Debugging
run these codes in adb
if this shows your device then proceed to this command :-
adb shell pm grant com.xda.nobar android.permission.WRITE_SECURE_SETTINGS
now restart your phone
and open XDA Navigation Gestures App and toggle Hide Navigation Bar button.
