Yii2 how to set page cache dependency on two tables?

Question

Yii

Good afternoon!
There is a CRUD controller for the model, let's say user, it organizes page caching through:

public function behaviors()
    {
        return [
            [
                'class' => 'yii\filters\PageCache',
                'duration' => 0,
                'variations' => [
                    Yii::$app->request->pathInfo,
                    Yii::$app->request->get(),
                    Yii::$app->language,
                ],
                'dependency' => [
                    'class' => 'yii\caching\DbDependency',
                    'sql' => 'SELECT MAX(updated_at) FROM user',
                ],
                'enabled' => Yii::$app->request->isGet
            ],
        ];
    }

Now the cache only depends on the last modification of the user table. In the view for index, I display data through the GridView, where there is a filter by the associated field, which is formed from a static function of another model:

...
[
                'attribute'=>'restaurant',
                'filter'=>Restaurant::nameArrayMap(),
                'value' => function ($model){
                   ...
                },
            ],
...

Question: how to make the page cache depend not only on changes to the main table, but also on the table used to build the filter?
