Thanks @RonanTheAccuser
i want to avoid a plugin just for this, is it possible want to try another method like adding codes to my functions files... or any other solutions...
You cannot unload these as auxin-front-2.woff is not enqueued but added via @font-face in auxin-icon.css, and symbols.svg is a sprite file declared as background in main.css.
And that's one of the reasons Phlox is a bad theme: it loads all kinds of unnecessary things that you are unable to unload or dequeue.
