Disable the automatic http(s):// addition in links

[David..]

Which file do I need to modify to disable the automatic http:// addition when adding a URL in CKEditor?

I wanted to add a link which needs to be clickable, but does not require the http(s):// protocol.

Example: magnet:?xt=urn:btih:01010846894794babc80c20d7d4fe21540a86632.....

This is a link but if you add that to CKEditor, it will break it by automatically adding the http in front: magnet:?xt=urn:btih:01010846894794babc80c20d7d4fe21540a86632

What do I need to edit to prevent that?
