@antoniodee I’ve checked your website and no Dashicons or JetPack CSS files are loading. I believe it was a caching issue when you made the test. Can you re-check appending a query string such as /?nocache so that whatever tool you’re using will not access a cached page (often when query strings are used, the cache is not triggering, at least that’s what happens with performance plugins such as WP Rocket, it depends on the caching service, just use a unique query string that you know it’s never been used so it wasn’t cached in the first place).
Also, you’re loading FontAwesome (same version: 4.7.0) twice. If you load the website with /?wpacu_unload_css=smr-fontawesome (which will unload one of the CSS files on-page request) appended to the homepage’s URL, you will notice the icons are still loading. You can also test using /?wpacu_unload_js=kirki-fontawesome-font which is the second file (JavaScript one) that loads it to check how the icons load.
I’ll definitely choose to unload one of these two assets.
