Disable Upserts of relationships #7544
Description
Describe the feature
Add the ability when configuring the connection to disable upserting relationships automatically for the library.
Motivation
It's incredibly easy for a developer to be upserting by accident, if something has been preloaded onto a model. We manage all relationships manually, or by using append. Is there a way of disabling upserts without manually having to use omit, or removing the relationship?
Related Issues
We currently are using a fork with the upsert code removed so it would be great if this could be configurable instead.
