You do not need to use tlsv1 method to be able to call
SSL_set_tlsext_host_name - you can use SSLv23_method and it should work
fine.

The SNI hostname is sent as part of the initial ClientHello, i.e. before
you've done anything with the server - so you have limited options to
avoid it. I don't understand why you would want to.
