Answer 1

idk, if it may help you, but I installed .Net framework 4.8 on 2012 R2 server.

Then I was able to use tls13 in my .net application.

It includes system updates:

In Windows Server 2012, Update for Microsoft Windows (KB4486081) is displayed under Installed Updates in Control Panel. In Windows RT 8.1, Windows 8.1 or Windows Server 2012 R2, Update for Microsoft Windows (KB4486105) is displayed under Installed Updates in Control Panel.

You also may try to install these updates only, but I am not sure about that at all.
