Hi hpmlo,
As far as I known, TLS 1.3 now is supported by like OpenSSL、NSS, but it seems still has no message about support on IIS or server2016, but I think it should be quick.If windows server beging to suppot it,it means there is user base and
requirements ask to do it.You could pay attention to Microsoft's official website. If there is news, they will definitely release it the first time.
Best Regards
Able
