TLS1.3 error 'Wrong version number' on non-TLS 1.3 Azure repository

I'm on the latest version of Git for Windows (2.33.1.windows.1). This particular Azure server does not support TLS 1.3 (according to ssllabs.com). Is there any configuration that can be done client-side to instruct GIT to use TLS 1.2?

Here is the error output:

This message doesn't mean that the client cannot fall back to TLS 1.2. That should happen automatically. Instead, this message usually means that the message the remote side sent doesn't look like TLS. That could be because you require a proxy of some sort (or are using one and it's failing), or because you have some machine or program (which could be a non-default antivirus or firewall) which prevents the connection from succeeding.
