+
+Instruct curl to use HTTP/3 to the host in the URL, with no fallback to
+earlier HTTP versions. HTTP/3 can only be used for HTTPS and not for HTTP
+URLs. For HTTP, this option triggers an error.
+
+This option allows a user to avoid using the Alt-Svc method of upgrading to
+HTTP/3 when you know that the target speaks HTTP/3 on the given host and port.
+
+This option makes curl fail if a QUIC connection cannot be established, it
+does not attempt any other HTTP versions on its own. Use --http3 for similar
+functionality *with* a fallback.
