Hello,
To add the knowsAbout to your schema, you may need to use and customize this filter on your site:
add_filter( 'rank_math/json_ld', function( $data, $jsonld ) {
$data['ProfilePage']['knowsAbout'] = 'knowsAbout';
return $data;
}, 99, 2);
If you’re not sure how to add this code, you can follow this guide:

Hope that helps.
