# `--tls-max`

VERSION defines maximum supported TLS version. The minimum acceptable version
is set by tlsv1.0, tlsv1.1, tlsv1.2 or tlsv1.3.

If the connection is done without TLS, this option has no effect. This
includes QUIC-using (HTTP/3) transfers.

Use up to TLSv1.0.

## 1.1
Use up to TLSv1.1.

## 1.2

## 1.3
