Not necessarily. You can use ARP and DHCPv6 and you don't have to waste time and power for DAD.
IPv6 does not do ARP, it does ND.
First of all, ND use is optional and, if ND is used, RA must be used. It means that, if RA is not used, ND can't be used. Then, the only reasonable protocol for address resolution is ARP.
Even if you use DHCv6, you still need ND. DAD is still performed on addresses assigned via DHCPv6.
That is a requirement by SLAAC because SLAAC has distributed states, which can be inconsistent. If RA is not used, there is no such requirement. Masataka Ohta
