There is no default option to disable that convenience feature. You would have to configure/override a metadata-template and configure an explicit "title" line to render the document name, title and/or version. There might also be some minor layout differences afterwards because you are effectively replacing the default yet specialized title renderer (when none has been configured explicitly) with a generic one.
Just to clarify, you could disable the rename action by removing it from the list of actions or setting its evaluator to false. What Axel is saying is that even if you do that, people could still do a rename simply by editing the properties and changing the name.
Then you'd also have to think about other file protocols such as CIFS, FTP, WebDAV, and IMAP, all of which could be used to do the rename.
