Deactivation of linking to posts or taxonomies

Hello,

The admin column uses the helper function rwmb_the_value to show the field value. You can use this filter hook to change the field value when showing on the backend. For example:

add_filter( 'rwmb_the_value', function( $output, $field, $args, $object_id ) {
    $post_field = rwmb_meta( 'post_xyfc97ama79', $args, $object_id );

    if( is_admin() && $field['id'] == 'post_xyfc97ama79') {
        if( $post_field ) {
            $output = get_the_title( $post_field );
        }
    }
    
    return $output;
}, 11, 4 );

change the field ID post_xyfc97ama79 with your field ID. Please get more details on the documentation https://developer.wordpress.org/reference/functions/get_the_title/
