Fontawesome JS render blocking

Minor issue but Google PSI is telling me that the file https://use.fontawesome.com/598b3d998a.js is render blocking on most pages other than my homepage. I’ve tried using the essential icons code found here: https://generatepress.com/fastest-wordpress-theme/ but this hasn’t helped. I’m not using non-default icons AFAIK on the pages it’s happening and I’ve got Autoptimise installed, what else can I try to defer this file or stop it being loaded on post pages?

Thanks!
