How to prevent the Kiosk mode being automatically enabled after disabling it?

Hey, Thanks for reaching out to us.

You can disable the kiosk mode on devices by removing the Kiosk policy associated with the device. The Disable Kiosk Mode action might be able to disable the kiosk mode only for a limited period of time. Kiosk mode will be activated on the device when the next device scan happens.
To remove the kiosk policy from a device, select the policy from the Policies tab and remove the desired device from the policy targets. You can also click on the desired device from the devices list in the Manage tab, navigate to the Policies subtab and remove the policy from the device by clicking on the trash icon next to the policy.
