How to customize 404 page in yii2?

Question

Yii

Is there any easy way to replace the view for 404 Exceptions? If the condition "if statuscode == 404, then this->render['404custom']" is set in the views->error.php file, then the content of the 404custom view is not rendered, only the title changes.
