How to disable automatically generated duplicate hreflang tags?

Technical Q&A
1

Hello,

I have added custom hreflang tags directly into my theme.liquid so that each language version of the website correctly points to the corresponding localized URL. The custom implementation works fine.

However, the storefront still outputs another additional set of <link rel="alternate"> hreflang tags in the HTML <head>, resulting in duplicates.
This causes SEO issues, for example:

  • Duplicate language alternates

  • Multiple x-default

  • Conflicting language signals for search engines

Here is how it looks in the source code (two separate hreflang blocks on the same page):

My goal

I want to keep using multiple languages, but I need to disable the automatically added hreflang block, so only the custom hreflang tags remain.

Question

Where exactly can I disable the automatic hreflang generation in Shopify?
Is there a theme or markets setting that controls this?

Storefront: https://www.stern-company.com

Theme: Dawn 7.0.1

Thank you!

There is no settings in Admin to do so.
However, previously it was possible for Support to disable this for your store if you ask them.
