UserManager.DISALLOW_CONFIG_MOBILE_NETWORKS should prohibit changing mobile network nostrings, but this policy can be bypassed on different devices:

Google Pixel 2 (Android 11) - Mobile Internet can be enabled/disabled via the Quick Settings panel

Xiaomi Redmi Note 10S (Android 13) and Samsung A73(Android 14) - Mobile networks section is inactive in settings. Mobile Internet cannot be enabled via Quick Settings panel, but by searching the word “Mobile Data” you can enable/disable mobile data usage.

Playback steps:

Set Device Owner mode
Set the UserManager.DISALLOW_CONFIG_MOBILE_NETWORKS policy.
Test the functionality in the Quick Dashboard, Settings and Search in Settings
Thank you!
