Hi,
Currently the highest minimum you can set is TLS 1.2. As a test, I tried to set it to TLS 1.3 via the REST API, and received below error:
{
"error": {
"code": "InvalidMinTLSValue",
"message": "The specified minimumTLSVersion 1.3 is unsupported."
}
}
I tested using Qualsys SSL Labs and the results were that TLS 1.0, 1.1, 1.2, and 1.3 are supported. If you have minimum set to TLS 1.2 you will not be able to use 1.0 or 1.1, despite the test results. If you have client capable of TLS 1.3 it should be able to use that.

Thanks.
