How to remove Nofollow attribute from links

I'm trying to optimize our Zendesk Guide content and improve our SEO. All of our article links include a nofollow attribute. We tried editing the code in the article_page.hbs and the header.hbs, but when I look at the article html the hyperlinks still include: rel="noopener noreferrer

Does anyone know how to make a global change to eliminate this nofollow attribute? Our articles typically link to our own website and we want to pass that link juice to our primary web properties or to related articles. Thanks
