You can't. On all stock roms the google play services is installed, which gives google full administrator access to the device with no way to disable it. Google has been known to abuse that privilege for things like location tracking without your permission [1].
Actually, I was able to effectovely disable Play Services and others using Marcel Bokhorst's 'NetGuard Pro', a clever firewall that allows detailed, as well as wholesale blocking. This allowed me to test the DeGoogled waters before finally flashing my phone (Essential PH1). NetGuard opened my eyes to what apps were requesting upon launch and it was quite disturbing. I ultimately ended up AOSP without any G services, and couldn't be happier. Signal has their websockets version on their site, and it indeed chews through battery faster, but a fair tradeoff for breaking away from incessant tracking and logging.
Even assuming you can get android to a state where it never automatically sends data to Google on its own with the privacy settings (I'm not sure how possible this really is) and you never use any Google apps, it's still a moot point unless you don't use any apps at all because pretty much all apps in the app store use google services / ads.
That's why you need one of the libraries that attempts to replace the google services.

How far can you get by using a vanilla Google Android but enabling all privacy settings and not using any Google services?
