If your devices only support TLS 1.0 or 1.1, they will not be able to connect to Azure after the retirement date because Azure will require TLS 1.2 or higher. There is no option to keep the older protocols enabled.

Many people use a simple Nginx or similar reverse proxy for this. It is the only way to keep older hardware working if the devices cannot be updated.
