This tweak replicates a feature in Chinese iPhone model by using Apple's own private APIs, which effectively writes to /var/preferences/com.apple.networkextension.plist. Either uninstalling this tweak, using the "Restore" button in Settings, or delete the file (and userspace reboot) will revert all changes made, except per app VPNs profile. You could manually delete them in VPN section settings. The file however store some other configurations, like VPN profiles. This tweak works on both iPhone and iPad (Wi-Fi/Cellular).
