Plugin is loaded on every page of the website instead of only out of stock pages

Hello,

Is there a way to disable the fonts from this plugin from loading on every single page of the website rather than just on the out of stock pages? Or eliminate them altogther and have the plugin just use the existing theme fonts?

These are loading sitewide:

Thanks!
