Hi Picht
We have looked into this however there was some questions regarding licensing that we need to look in to. In the mean time you can try the following...
1. Disable 
Font Awesome in the 
General -> Typography tab of your template settings.
2. Add the following to the 
Custom Code -> Head Custom Code field...
<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.5.0/css/all.css" integrity="sha384-B4dIYHKNBt8Bc12p+WXckhzcICo0wtJAoU8YZTY5qE0Id1GSseTk6S+L3BlXeVIU" crossorigin="anonymous">
