I'm less familiar with AWS. But on Azure, you can have private storage accounts which aren't internet routable so they wouldn't even be able to hit the endpoints to rack up charges. It's a bit ridiculous that you'd have to go that far to avoid being charged for unauthorized access, but I'd be surprised if AWS and GCP didn't have similar capabilities.
