What versions of TLS does the "Do not use TLSv1" option disable?

Problem

On an HTTPS port in API Gateway, there's an option named "Do not use TLSv1." Does this option disable TLSv1.1 or TLSv1.2 or does it disable only TLSv1.0?

Resolution

Only TLSv1.0 is disabled. It has no effect on TLSv1.1 or TLSv1.2. The option to disable TLSv1.1 and TLSv1.2 on an HTTPS port was not added until version 7.5.2.
