You can't easily do that. However since you mentioned that you are developing a Kiosk mode you should switch the device to Assigned Access first
In assigned access many of the shortcuts ALT+F4 and CTRL+ALT+DEL are disabled and your app will run in full screen mode, which means there is no risk to being dragged around.
The hardware Windows button is disabled as well so you are guaranteed that your app always runs as the main app.
