Hi Mayank04,
Welcome to the MSDN forum.
AFAIK,
the TLS 1.3, being a recent specification is not supported by the native SCHANNEL implementation of ANY version of windows (even 2016) now. MS do not support TLS 1.3 yet (even not with 2019).
Since our forum is to discuss the .NET Framework installation issues, you can also
redirect to
https://social.technet.microsoft.com/Forums/en-US/home?category=windowsserver or
https://forums.asp.net/ for better support, thanks
for your understanding.
Best regards,
Sara
