How to disable autocreation of new branches after publishing changes

Summary:

We were told that best practice is to have one project, one workspace, and multiple branches (one for each functional area) - However, when I publish code it is automatically creating a new branch. How do I disable this? I would prefer to switch branches to the applicable branch that is tailored to that specific area. With the understanding that I will need to Pull from the main branch every time to refresh it.
