No, you have to configure IPv6, otherwise processing is not done.

See the ifconfig option (which is default if you do not configure any IPv6):

     ifdisabled
             Set a flag to disable all of IPv6 network communications on the
             specified interface.  Note that if there are already configured
             IPv6 addresses on that interface, all of them are marked as
             "tentative" and DAD will be performed when this flag is cleared.
