question: can I allow plain and http2 at the same time?

[andykais]

Hi, I want to know if I can enable plain http protocol for http1.1 and https for http2 in the same web server.

The use case is a local web app. I want users to be able to take advantage of http2 speed, but also use http1.1 over plaintext if they do not want to set up certs locally or deal with the advanced -> proceed to unsafe option.
