Load views without Routes in v6

Hi, 'am using core version, and I trying of load views maybe from url (ajax) or from the same html file (using all views into a single html page), and I did it. but in version 1

now I want to migrate to v6 and I see only is possible defining the routes, as in react. but can I do it using core version avoid of defining the routes, I mean without using routes variable ?

No, v6 requires to use routes
