Remove Date

Hello,

Thank you for contacting Rank Math.

These properties are recommended by Google for your schema markup.If you still wish to remove this you can use the following filter:

/**
 * Filter to change the schema data.
 * Replace $schema_type with schema name like article, review, etc.
 * @param array $entity Snippet Data
 * @return array
 */
add_filter( "rank_math/snippet/rich_snippet_{$schema}_entity", function( $entity ) { 
         unset( $entity['datePublished']);
         unset( $entity['dateModified']);
         return $entity;
});

The code is to be customized and added to your theme functions.php file.

Hope this helps you.Thank you.
