To change the Yoast SEO generated sitemap file URL, you can follow these steps:
Alternatively, you can also manually edit the sitemap file URL by modifying the Yoast SEO settings in your website's file system. You can access the Yoast SEO settings file located in the wp-content/plugins/wordpress-seo/inc/ directory and make changes to the sitemap file URL there.
Make sure to clear your website's cache and notify search engines of the change to ensure that they are indexing the updated sitemap file URL.
