yes the code is – works with custom post types too:

<?php
 
function acf_set_featured_image( $value, $post_id, $field  ){
    
    if($value != ''){
	    //Add the value which is the image ID to the _thumbnail_id meta data for the current post
	    add_post_meta($post_id, '_thumbnail_id', $value);
    }
 
    return $value;
}

// acf/update_value/name={$field_name} - filter for a specific field based on it's name
add_filter('acf/update_value/name=cursusfoto', 'acf_set_featured_image', 10, 3);
 
?>
