It probably won't work with dhcp option 61 authentication but may with dhcpv6 prefix delegation as shown below
Tp link AX is on latest firmware
IPV6 on (advanced menu option)
Dynamic IP (SLAAC/DHCPv6)
advanced settings: DHCPv6
prefix delegation enabled
DNS address: get dynamically from ISP
IPv6 LAN
SLAAC + stateless DHCP
MAC Clone: Use Default Mac address
