Answer 3

Good day.
You can do this (register in the configuration file)

'on beforeAction' => function($event) use ($params) {
        if(!Yii::$app->user->can('admin')){
           // закрывается доступ для некоторых действий
            if(in_array($event->action->id, $params['no_section']))
            {
                return Yii::$app->response->redirect(['main/default/no-section']);
            }
        }
        return false;
    },
