IPv6 support on MAX BR1 Mini with 8.1.0 firmware?

I just got a MAX-BR1-MINI-LTEA-W, which I promptly updated to firmware 8.1.0 and all seems to be fine. Except that I cannot find any mention in the configuration interface of IPv6, and unsurprisingly, it looks like I don’t have an IPv6 address.

The manual mentions IPv6 support. I see mentions in this forum of asks for IPv6 support from 2013, 2016 with promises that it will be there at the latest in June 2017.

How do I enable it?

Thanks.

I’m looking to see if it’s enabled by default. If so how to disable? My service is w/ AT&T and I vpn into work. VPN keeps dropping and searching consistently brings up that IPv6 causes issues. Is there a way to control IPv6 on the BR1 mini???
