Those are broken cryptographic protocols used by applications with the need to secure the transmission transport part of the communication. Think of web services or mail services.
It is not at the OS level. It is at the application level. Therefore, if you are charged to disabled these old and broken versions of the TLS and SSL, you must learn what configuration must be changed to the application to prevent it from using it.
