Using the hook

If it can helps anyone, the code below solved my question

function clean_lucky( $args ) {
  $args = array(
    'container' => 'nav',
    'container_class'	=> 'main-menu',
    'items_wrap' => '<ul>%3$s</ul>',
    'menu_id'	=> '',
    'menu_class' => ''
    );
  return $args;
}
// add the filter 
add_filter( 'lwpamf_wp_nav_menu_args', 'clean_lucky', 10, 2 );
