How can I fix 302 status codes warnings on my website?

Hello,

When I crawl my website with SEOSpider of SEMRush, I get hundreds of “warnings” related to temporary redirects, or 302 status codes.

The issue comes from a link, in the footer, thus on every page of the website, heading to another Shopify store, but this one, password protected.

How can I fix that ?

Is it something to be done in robot.txt?

Is it to “noindex” the link in the footer? If so, how can it be done in Shopify?

Thank you for your help!
