Stop GMS Firebase Indexing from collecting all of the personal data

When I was playing with settings on my Nokia 6.1 Plus running a stock ROM Android 10 with bootloader unlocked and rooted with Magisk v21+, I noticed that **Firebase App Indexing** that comes under **Google Account Preferences** was collecting all of my *personal* data. Of course, **GMS** was the culprit. Here's the proof: This was the message that I received from the bank for the transaction that I made yesterday. Every message that I sent and received had been collected in this given format. Also, many apps that use Firebase API sent these kinds of information. I'm a guy who thinks about user privacy all-day, so I've used: - [Nuked_Script](https://forum.xda-developers.com/apps/magisk/module-tool-atteryerformancerivacy-t4131715) Magisk script that is used to disable trackers and ad services. - AFWall+ for Firewall (root). - Bouncer - Temporary App Permissions. - AdAway for nullifying ads (root) - ads on Gmail, Twitter, Instagram still exist though - Bromite webview and browser (Webview Switcher module). When I turned the developer options off, Firebase App Indexing options also turned off (_I mean **hidden**_). So, does it mean that it stopped collecting my data? I still doubt that. How can I stop this from happening? P.S: I'm used to using Google Apps. But I don't want to give them such personal data.
