How to assign multiple global IPv6 through 5G modem to each connected device

Hi Experts.

Anyone have knowledge on procedure to assign multiple global IPv6 through 5G modem to each connected device?

It should work Without Perfix deligation.

I want to config the router as DHCP agent so all connected devices to the router can get their seperate IPV6 address from statefull DHCPv6 server on mobile core network.
