How do you set HSTS security headers?

Hi there - I am looking to enable HSTS on our domain, and although I have found a Webflow Universoity article on the subject, the options do not appear on my account as per the article.

This is the article: https://university.webflow.com/lesson/custom-security-headers?topics=site-settings#how-to-enable-hsts-response-header which says to go to " Site settings > Publishing tab > Advanced publishing options ."

However, when I go there, this is what I see:

Anyone got any ideas where this option may be?

@hugorodgerbrown - If you get an enterprise plan that is an option.

We’ve actually had to move clients away from Webflow and to other platforms like Netlify who provide HSTS in their base plans, as Webflow is choosing to make a cash grab and upcharge users roughly $10k for access to an industry standard security feature.
