How to Hide Status Bar in Android Devices?

Go to Kiosk Launcher > Home Screen > Use system status bar. And then disable the button.

You can find this feature via Policy & Kiosk Config Files > + Create Config File > Kiosk.

In Devices > Provisioning Templates > + Create template, choose the config file you just set and click 'save'.

This template will generate a QR code that used for device enrollment. In this way, when you bind the Android device to the MDM software, it will automatically hide the status bar.

Go to Device Enrollment > Device Owner > 6 times Tap. Enroll your Android device by scanning the QR code.
