How to update apps without logging into a Google account for multiple tablets?

We are a company that sets up multiple tablets for our customers with the same Google account. Our customers are complaining that they are constantly being logged out and have to log in again to update our apps. Is there any way we can have our customers update our apps without having to constantly log into the Google account? I saw there is Aurora Store, but I don't want to risk losing our Google Play Console privileges if Google finds out our customers are downloading from there. What is the best approach here?
