If you need this procedure, please open a Severity 3 support case and note in the case you are doing so due to this post.
Please note, the procedure is meant for disabling TLS 1.0/1.1 for the ZVM service.
For VRA service, there is no workaround to disable 1.0/1.1 prior 8.5 version. In the 8.5 version and above, the VRA enforces TLS 1.2 as the minimum protocol. When attempting to connect with a protocol lower than TLS 1.2, the 8.5 VRA will reject the connection.
