I'm not sure what remaining IPv6 you'd see (or concerns you), but:

  • Disabling WAN6 should stop native IPv6 Internet from your ISP on WAN
  • You can remove the ULA prefix from the Interfaces page
  • Remove the IPv6 address and prefix from all interfaces
  • Disable RA/DHCPv6 on all Interfaces
  • You can also disable IPv6 routing in sysctrl.conf
