Could try disabling it in your router... provided you have the rights to do so. YMMV depending on your area's available IPv4 pool though. On most newer Asus routers, IPv6 has it's own tab... may not be the same for all brands though.
Alternatively, you could try slingshotting through a VPN service. There are some free ones out there for Android (with limited usage rules), but you may have to deal with ads.
