Hiding Breadcrumbs on Specific pages

Hello @misterchew,

Thank you for contacting the support.

Here is the filter to remove the BreadcrumbList Schema:
https://rankmath.com/kb/filters-hooks-api-developer/#remove-breadcrumblist-schema

Example:

add_filter( 'rank_math/json_ld/breadcrumbs_enabled', function( $value ) {
	if ( is_page('about') || is_page( 'contact' ) ) { // Please change the about & contact with your page slug.
		return false;
	}
	return $value
} );

Hope that helps.
