Hi @axibert
Yoast SEO includes filters that allow you or your developer to customize many of our plugin features. These filters are documented inside the plugin code. We also have a developer portal where you can find more information about filters and even check out some examples of how to use them.
Typically code snippets are added to your theme’s functions.php file. If you’re not familiar with using code snippets, we’d like to refer you to the WordPress documentation on how to use a filter.
We would like to refer you to our available documentation on how to modify the Yoast SEO breadcrumb output – https://yoast.com/help/implement-wordpress-seo-breadcrumbs/#pathway
Unfortunately, we can’t provide specific advice on how to implement these filters on your website, as custom code is already outside of our scope of support.
We are going ahead and marking this issue as resolved due to inactivity. If you require any further assistance please create a new issue.
