WP Widget args

Is there a way to customize the WP Widget markup?
I saw 
```php
$empty_widget_args = [
			'widget_id' => $this->get_name(),
			'before_widget' => '',
			'after_widget' => '',
			'before_title' => '<h5>',
			'after_title' => '</h5>',
		];

$this->get_widget_instance()->widget( $empty_widget_args, $this->get_settings( 'wp' ) );
```
But there is no filter there.
