A couple of options come to mind. The short answer to your question is "No." Here are some other options:
1. If the users can be trusted, just 'pin' the baselined version of the files. They will not be able to check-in/check-out the file and "Getting latest version" will get the pinned (baselined) version.
2. If the users would unpin the file in order to get around this, you can checkout the file yourselfe in the active project and share-branch the baselined versions of the files to a different project that they cannot check-out from. This is explained pretty well in the help file.
