@sergiourra Just put it to functions.php in your theme.

Hello all, I did this solution, hope it help for someone.

add_action('wp_loaded', 'show_all_filters');
/**
 * List of all filters with their function names.
 */
function show_all_filters()
{
    remove_filter_by_method_name('filter_robots');
}

/**
 * Remove needed filter from list
 *
 * @param string $method_name Name of the method called to the filter.
 * @param int $priority Set the priorite from that filter if we need to remove just from it.
 *
 * @return void
 */
function remove_filter_by_method_name(string $method_name, int $priority = 0)
{
    global $wp_filter;

    if (isset($wp_filter['robots_txt']->callbacks) && is_array($wp_filter['robots_txt']->callbacks)) {
        foreach ($wp_filter['robots_txt']->callbacks as $callback_priority => $callback) {
            foreach ($callback as $function_key => $function) {
                if ('filter_robots' === $function['function'][1]) {
                    $priority = 0 === $priority ? $callback_priority : $priority;
                    unset($wp_filter['robots_txt']->callbacks[$priority][$function_key]);
                }
            }
        }
    }
}
