To allow AdGuard launch after system boot, you'll need to enable this feature in system settings by yourself for the app.

Sadly, for now universal method to show user this kind of system settings does not exist, because every manufacturer (XIAOMI, OPPO, Vivo, Asus, etc.) make their own implementation of auto-launch setting in different places of system or app setting, those state can't be read from application.
