Disable remove movie from library option

Is there any option available to disable the remove movie from library option . I have movies in NAS which has SMB file sharing disable scheduled for some particilar time to discourage kids from playing movie during study time. But if they starts to play movie, the pop up comes asking them to rmeove movie from library since the file is not avaialble.

Any advise on this will be help full. can i amend any xml file to remove the option .
