Is it possible to set up a redirect from non-existent https to http?

Question

Web development

Is it possible to set up a redirect of all pages of the site from non-existent https to http, i.e. if https is not configured on the site in principle?

Answer 1

No, in order to set up a redirect with https, in any case, you must have a certificate for the domain from which the redirect is made.

Answer 2

No, until a trusted https connection is established, the browser will not trust the received information.
The ability to transfer the browser to an insecure connection will pull on a very, very serious vulnerability ...
