If you want to improve your privacy from these stock apps, you might be able to flash LineageOS. Be warned, though, this will utterly destroy your security. If you want security and privacy, get a Pixel 4a or newer and flash it with GrapheneOS.
Back within the constraints of the stock OS, though, make sure you have revoked all the app's permissions. Try to use an app firewall like NetGuard and block its internet access, too. Its a system app so this may not be effective, but its worth a try.
