Is it possible to completely disable ipv6 in NetBSD 10

[Will Senn <will.senn%gmail.com@localhost>]

    In other OS'es I am able
      to completely disable ipv6 - usually via:
      
      vi /etc/sysctl.conf
      net.ipv6.conf.all.disable_ipv6 = 1
      net.ipv6.conf.default.disable_ipv6 = 1
      
      and disabling ipv6 for each nic.
      
      or selecting no for ipv6 for the interface at install...
      
      How can I turn it off for netbsd? Is it possible on a nic by nic
      basis or a sysctl?
      
      Thanks,
      
      Will
