Several years ago, I wrote a Greasemonkey script to do this. I haven't used it in years, and am not sure if there's an alternative for Brave browser (my new standard).
It basically looked for all the "a" elements in the DOM and:
1. Set the href to call a JavaScript void
2. Set the element style's text-decoration to none
3. Set the element style's background color to #f3f315
