I understand and do not have a real solution, as I do not use the apps, so I cannot test. If there is no solution at all, you might want to consider to install e/ OS. This comes with microG included what replaces/fakes some “important” google functions. With this OS the communication with google is very minimal to zero. It has an own play store and the stock apps are as far as I know forks of open source apps. e/OS is already based on Android 10, that would mean, switching to e/OS should work without data loss, however when you do not like it and you want to go back to FPOS this would be downgrade with def. data loss.
