How can I enable the HTTP/3 (QUIC) in HAProxy?

Question

I found the fact that HAProxy 2.3 higher supports HTTP/3 (QUIC) through this link.

I’d like to know how to enable HTTP/3 (QUIC) in HAProxy.
I can’t find any data related to this anywhere.

I already downloaded the latest HAProxy source (v2.4-dev5) and built it with USE_QUIC=1.

Any suggestions would be great!
Thanks.

I think you are mistaken as to the current level of support. From the announcement of v2.4-dev5:

Fred's experimental QUIC code made its entrance! OK OK OK please calm down, it's just a part of the code that's needed to get merged to continue the required infrastructure changes and there is absolutely nothing functional at this step. I think at best it will handle a handshake.
