Not in the legacy editor. But in the designer’s edit mode, you can do this now, and mid 2025, all legacy editor users will be automatically migrated to client seats and the designer’s edit mode at no added cost.
In designer editor mode, you can just publish the site to staging only, which is what you’d do for non-CMS content.

- Make your edits in the CMS
- Change the status of the CMS item from draft changes to stage for publish
- Then publish the site to staging only
