No, there isn't.  AFAIK a LL address is always required for IPv6. And it
seems the kernel will add one even if you have manually configured one
before bringing the interface up.  That's possibly a kernel bug?

But I believe most ND transmits are disabled by setting NOARP. And the
rest can be avoided by tweaking the /proc/sys/net/ipv6/conf/<iface>/*
