Remove Moderated content tab

Hi, you need to implement a custom hook, something like that:

/**
 * Implements hook_menu_local_tasks_alter()
 */
function MYMODULE_menu_local_tasks_alter(&$data, $route_name, RefinableCacheableDependencyInterface &$cacheability) {
  if ($route_name == 'system.admin_content') {
    unset($data['tabs'][1]['content_moderation.content']);
  }
}
