Do not cover the top of the screen

[Android Central Question]

Hi. I have androd Honor 9 lite and I am not able to disable 'do not cover the top of the screen' function. I am not finding any option like touch-disable mode on my settings and also upper volume button with lock screen button pressed simultaneously, is not working to disable this mode.I am not getting a 'More' option in 'Smart Assistance' as well. Really need to disable it asap as I use to keep the phone in an transparent armband. Kindly help.
