You can enable the Legal Hold File Lock (F-lock) feature to lock a file from being changed and force a file to become a new version after any edits have been made.
Once a file has been locked, you cannot unlock it and it becomes Read-only.
It will be identified as a locked file and a hash value ensures that file contents will not change.
If you want to edit the file after locking it, you must check it out, edit it, and check it back in. The only option should be to create a new version.
This feature is turned off by default, so you must activate it to use it. For details, see Activating the Legal Hold File Lock Feature.
