Hello @Jay ,
Thank you for posting here.
After my research, TLS1.3 is not supported on Windows 10.
The following table displays the Microsoft Schannel Provider support of TLS protocol versions.
For more information we can refer to link below.

Here is a similar case with marked answer for your reference.
TLS1.3 is it supported?

Hope the information above is helpful.
Should you have any question or concern, please feel free to let us know.
