Hi Maria,
1. No, unfortunately that only works with the post or product elementor modules.
2. There is no option for that, but it is possible via custom code. I do not recommend that if it is avoidable, as random ordering performance can be very bad.
Try adding this custom code to the functions.php in your theme/child theme directory. Before editing, please make sure to have a full site back-up just in case!
add_filter( 'asp_query_args', 'asp_order_by_rand', 10, 1 );
function asp_order_by_rand($args) {
$args['cpt_query'] = array(
'fields' => '',
'join' => '',
'where' => '',
'orderby' => 'RAND(), '
);
return $args;
}
