Remove Yoast Breadcrumbs Schema

If you want to remove the schema that the Yoast SEO plugin adds for breadcrumbs, use the following snippet:

add_filter( 'wpseo_schema_graph_pieces', 'remove_breadcrumbs_from_schema', 11, 2 );
add_filter( 'wpseo_schema_webpage', 'remove_breadcrumbs_property_from_webpage', 11, 1 );

/**
 * Removes the breadcrumb graph pieces from the schema collector.
 *
 * @param array  $pieces  The current graph pieces.
 * @param string $context The current context.
 *
 * @return array The remaining graph pieces.
 */
function remove_breadcrumbs_from_schema( $pieces, $context ) {
    return array_filter( $pieces, function( $piece ) {
        return ! $piece instanceof YoastWPSEOGeneratorsSchemaBreadcrumb;
    } );
}

/**
 * Removes the breadcrumb property from the WebPage piece.
 *
 * @param array $data The WebPage's properties.
 *
 * @return array The modified WebPage properties.
 */
function remove_breadcrumbs_property_from_webpage( $data ) {
    if (array_key_exists('breadcrumb', $data)) {
        unset($data['breadcrumb']);
    }
    return $data;
}

This code removes the Breadcrumbs Schema from all site pages. Add this snippet to your theme’s functions.php file (preferably in a child theme).
