I'm #DeGoogle a device which I prefer it has the Google Services. The only way I can think of it is:
1. Uninstalling by #adb some apps that I don't need (like Youtube por Gmaps).
2. Using a #vpn (#Netguard) to block the conexion at the apps I don't using at the moment.
3. #Freezing some system apps with #Shizuku and #Hail apps.
