What? No. You connect a device, and SLAAC (and optionally DHCPv6, on enterprise networks) configures everything. It just works.
SLAAC is more than capable of sending DNS settings to devices. There's no manual configuration involved.

SLAAC does not do DNS. Clear as day?
Some older devices [1] do not support RDNSS. I haven't run into them, but if you're at all worried about it, you can run DHCPv6 in parallel just to hand out DNS settings.
Personally, I just use SLAAC (with RDNSS) and it just works.
