regex – How to change syntax highlighting of URLs in Visual Studio Code

One answer is to just turn off linkifying of URLs altogether:

"[html]": {
    "editor.links": false
  },

But what I’m trying to do is keep that feature and turn off the actual underlining. (It’s because I have a very compact font and line spacing and there isn’t room for the underlining without bleeding into the next line!)

I’ve searched the VSCode theme files and they don’t seem to make any mention of URLs or links or any regex involving “http.*” or anything. So where the heck is that syntax highlighting rule defined and how can I tweak it?
