Guided Access (других вариантов я не видел)
Designed with security in mind, Apple’s iOS 11 enables the use of ‘Guided Access’. The feature allows you to control and limit the use of the device to just one app of your choice. Found in the iPad’s general settings, it is a simple way to prevent users from switching in and out of other apps, or accessing additional features on the iPad.

1. Select: Settings > General > Accessibility > Guided Access > On
2. Set a passcode (tip: avoid choosing a combination like 1-2-3-4-5-6). A six-digit code that will be memorable, but not easily guessed works best.
3. Next, press the home button to return to the home screen. Open up your chosen app and once loaded, triple click the home button so that the Guided Access screen appears. Press Start.
4. Guided Access mode will begin, and your device will be locked down into one app.
5. If you need to disable touch on certain areas of the screen (e.g. on a webpage to prevent users from typing a new URL into the address bar), access your Guided Access screen again by triple clicking the home button and entering your passcode.
6. Ensure that: Touch Option > On. You will now be able to draw a shape around any part of the screen and adjust the position and size by pulling the corner circles. Press Resume (top right corner). This part of the screen will no longer react to touch.
