Is it possible to configure things so that Merge syncs all data except for a particular endpoint?

We can't turn off particular common models since we have to store all possible data, as our platform can't predict what a user is ultimately going to pull from our API. However, permissions for data can be modified on a credential level, so your customer can opt not to enable access to that data, this way Merge won't store any anything for that endpoint since we won't have access in the system!
