How I make my Jupyter notebook script locked?

I have multiple scripts using the IRkernel on Jupyter notebook. I have to put them on a server, but I want to make it not editable and not deletable, it is kind of lock. The aim is that people can only run the script. I have already tried things, mainly by modifying the metadatas like that :

"deletable": false,
"editable": false,
"trusted": true }

But when it would be on the server, others people can modify the metadatas, so it is not really what I want. Is there a way to make my script fully locked and that nobody can editable it ?
