Setup check for my Android phone

1. I have paid versions for both, DNS having a 5 year plan, and has Adguard DNS filter, Hagezi pro++, OISD, Dandelion and threat intelligence filters. Don’t know how to deactivate NetShield though, it just deactivates itself as there’s no button for it cuz it knows I have external DNS 2. I actually didn’t think I could do that cuz it’s not an option in the per app settings, it’s only accessible in the data usage window, weird. But I have some “apps" that’s just a string of numbers… and some others I don’t if I should disable, such as Android OS, Play Service, Nothing Launcher, Essential apps, config updater, private compute services? Just to name a few, again I see lots of just strings of numbers of “apps". 3. There might be some apps that might be able to do that, like one of the tax apps. But banking is impossible since virtually any banks WANTS me to install their apps as their 2FA to transfer money , but ye I’ll try my best to find apps that could use websites, luckily I don’t have many proprietary apps 4. Probably not? I can’t remember much personal accounts like social media accounts, I still have reddit and twitter accounts but they are for miscellaneous purposes and would like to find apps for each of them that can locally save posts/subreddits and follow people I did use ADB to disable a lot of junk apps like Google and nothing apps, I used ADBZero, it’s a web based ADB and I disabled all of the recommended apps from UAD database. Thanks!
