You should do nothing. --disable-ipv6 is not a valid option, so the
configuration script will ignore it.

If you do not want to use IPv6, make sure that your system has no
IPv6 interfaces. Bind will then not do anything with IPv6. You can
also specifically disable all IPv6 support by using listen-on-v6 {  none; };
within the options field in your named.conf.
