You can’t. Google Play services is a core part of Android, so it’s always going to be there. You could uninstall the app from your phone, but you’ll have to keep it on your phone if you want to use any other apps that need it.
If you uninstall Google Play Services, it will not affect any other apps on your phone. You can still use the app store and download apps from there. The only thing that may happen is that some apps may not work properly or at all.
It is not safe to delete data from Google Play services. Deleting the data will make it unavailable for use until you re-download it.
