No, you have to send S,SET PROTOCOL 6.1 each time you connect if you want it. The API does not have any ability to retain a setting. This is a standard behavior of REST APIs: the server does not store any information about a connection.
The API defaults to the oldest supported protocol for backwards compatibility reasons. It is preferable to force the user to specify a newer protocol if they want, so as not to break existing code each time a new protocol is released.
