You may want to consider whether it's useful to do this.
DHCPv6 CAN give you an address (although unlike with DHCP for IPv4,
not every DHCPv6 server is configured to do so) but it can't give you
a subnet prefix length or a default gateway, so local communication
will have to depend on the "on-link assumption" which is considered a
security flaw by many and has the potential to cause timeouts when
trying to communicate with IPv6 destinations. And non-local
communication won't be possible.
