Test with browser without HTTP/2

[demisgomes]

I wonder if there is a possibility of test a host accessing it without the HTTP/2/. In Chrome, it is possible using the flag --disable-http2, and in Firefox can disable the support to HTTP/2 in about:config. However, the webdrivers open the browsers in default mode, i.e., with support to HTTP/2. It is possible change some part of the code to change the browser behavior, forcing it to use HTTP/1.1?

Thanks!
