@jaap115 You are able to programmatically edit the breadcrumbs pathway from within your theme’s functions.php file by using the wpseo_breadcrumb_links
developer filter. You can find some example code on how to use this filter available here.
In addition, wpseo_breadcrumb_single_link is another developer filter that is available, which allows you to edit indiviudal items in the breadcrumbs pathway. Example code usage for it can found here.
When using developer filters to customize the breadcrumbs in functions.php, we recommend using a child theme so as to preserve your changes.
If you aren’t sure of how to implement customizations using a developer filter in functions.php we would recommend reaching out to your theme provider, 3rd party WordPress developer, or Yoast Partner for additional assistance.
