Refer to http://nginx.org/en/docs/configure.html for details.
When configuring nginx, it's possible to enable QUIC and HTTP/3
using the following new configuration options:
using the following new configuration option:
--with-http_v3_module - enable QUIC and HTTP/3

are several of those available on the market:

The HTTP "listen" directive got a new option "quic" which enables
QUIC as client transport protocol instead of TCP.
The Stream "listen" directive got a new option "quic" which enables
QUIC as client transport protocol instead of TCP or plain UDP.
Along with "quic", it's also possible to specify "reuseport"
option [8] to make it work properly with multiple workers.
