Hey dwrfgtx,
If you have the device with Screen Time, there's a way to turn off Screen Time. Here's how:
Use Screen Time on your iPhone, iPad, or iPod touch
If you're using Family Sharing to manage a child account
1. Go to Settings and tap Screen Time.
2. Scroll down and choose your child's name under Family.
3. Tap Turn on Screen Time, then tap Continue.
4. Set up Downtime, App Limits, and Content & Privacy with the limitations that you want for your child, or tap Not Now.
5. Tap Use Screen Time Passcode, then enter a passcode when prompted. Re-enter the passcode to confirm.
6. Enter your Apple ID and password. This can be used to reset your Screen Time passcode if you forget it.
Let us know if this helps!
Best regards.
