Yeah. Before OneUI 8, you could set up a custom ROM on a Samsung phone too. Short of that you can disable google services. Use non google apps from F-Droid or Aurora Store. You can also use ADB to uninstall system-level APKs. Though the only way that I know of to fully de-google is to install a different OS.

Not all android spies on you. Have you ever tried GrapheneOS? It’s very secure and pro-privacy. Technically it’s not android (if you really want to nitpick), but you need a Google Pixel to run it.
