Disable or Change Ctrl + Alt + Del for Kiosk Mode

I've successfully set up Kiosk mode on a Windows 10 Enterprise PC. I have it so that it auto logs in with the local user name and it launches the app. I've disabled Ctrl + Esc via Keyboard filters and also Ctrl + Alt + Del. My main goals is to restrict users from entering those key combinations. If they do, it ends Kiosk mode and they are sent to the login screen showing the user name and a blank password field. They do not know the password and they don't have the power button available to them to restart to trigger the autologin.

I just need Ctrl + Alt + Del to go away and this setup will work. I've even tried using SharpKeys with no luck. I'm starting to think this is a limitation of the Kiosk mode in Windows 10.

I was able to create a scheduled task to restart the computer each time the local user is disconnected (when someone presses Ctrl + Alt + Del), however it restarts when I remote into it with my admin account! DOH!

Any suggestions would be helpful at this point. I work for the government, so funds are tight and this is what I have to work with.

    I applied the registry change, but I'm still able to use Ctrl + Alt + Del and end Kiosk mode. The user is taken back to the log in screen and they see the user name with the password field.

    Hi，
    @Emily Dullum
    Thanks you waiting for reply, I do appreciate your time and effort! I hope we can find a solution! above all, did you find any changes after applying the registry change? if so and failed, what's worse you don’t like the change, you can just delete the Scancode map in the following link to restore
    Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout

    If there aren’t any changes, that’s unusual, I suggest you have another try that create the Scancode map manually.
    As MSFT, we don’t suggest using third party tools as you had used, maybe it’s due to incompatibility even the Sharpkeys doesn’t work in kiosk mode.

    Here is the detailed usage of editing Scancode Map

    The solution or workaround if you will is creating a scheduled task to restart the computer each time the local user is disconnected (when someone presses Ctrl + Alt + Del) :(
