R7000 Dual Stack setup?

Hello all,

I have a device or two that is unfriendly with ipv6, primarily my nest thermostat v1. I tried looking and searching google but I could not find a way to setup a dual stack on the r7000. Nor did I find info regarding open firm wares support for this router that would allow dual stack ip. Perhaps I misread or didn't understand? Any advice would greatly be appreciated!
