ipv6_addrs_XXX doesn't do the trick, however this one does:
ipv6_ifconfig_lagg0="fe80::3/64"


lagg0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9014

For a reason that eludes me, the interface still insists on getting an
automatic link local address, but I'll look into this ;)
