Like mentioned, CarPlay doesn't start unless connected to a supported headunit, but do you mean Do Not Disturb is being enabled when they're moving around? The "Do Not Disturb While Driving" feature can only be manually turned off on the device (Settings >> Do Not Disturb >> Do Not Disturb While Driving") and I don't believe there is a way to disable it via config profile. Surprised it would enable from walking, though. My experience is you'd need to move pretty fast for the M-chipset to think you're in a car.
Hi all please see the screenshot
I could be wrong, but the image in the top post appears to be a pane that appears during setup assistant.
DNDWD, when it kicks in, is just a simple notification on the lock screen that reads "DO NOT DISTURB WHILE DRIVING - You will not receive notifications while you are driving." You can tap on that notification to bring up a button that says "I'm Not Driving."
I'm not yet current on my JSS, but on mine, I don't see an option to skip a DNDWD pane in a prestage, unless it's grouped under "new feature highlights." You could try that - create a prestage for the device, tell it to skip "new feature highlights," and reset the device to see if that DNDWD pane goes away.
