I was going to suggest if you have all the content you want in your NFO file, you could go to the actual file and make it read-only. Unfortunately, I just checked that with my setup and it didn't work. I am using my main Windows computer as the server right now and just pulling the data from my NAS. I set the nfo file to read-only, but that didn't seem to stop the file from being updated.
