I'm afraid there is no utility method for that in response->redirect().
You can pass in parameters as a string:
dispatcher->forward() does accept a params key, although it's not the same as redirect.
i think the answer is you cant, but you can redirect to /myroute?param1=yes¶m2=no
after that //print_r($_GET);
As an afterthought, if you need named routes you can hook it up with url:
'for' => 'namedRoute',
]) . '/' . join('/', ['my','custom','params']));
