When will firmware for the Nokia 5G home router be updated to add true router functionality?

I have StarLink Best Effort and T-Mobile Home internet. T-Mobile is beating StarLink in most speeds. I'm getting up to 200 mbps on 3 bars that occasionally drops to 2 bars. Both providers are using CGNAT (Carrier Grade Network Address Translation). CGNAT is just a super big LAN like we use except our subnet mask allows about 250 ip addresses and a CGNAT allows millions of non-public IP numbers. Starlink allows port forwarding on their router but all it does is let you double NAT instead of triple NAT. Most routers use DHCP to give out local ip numbers. You set up port forwarding on you router to send an incoming port number from the internet to the correct IP number  on you network, If you have another router connected to the first router, port forwarding will not work on the second router because you are double NATing. With CGNAT we are always the second router and I suspect there is no way for T-Mobile to provide port forward on CGNAT. T-Mobile is providing me a IPv6 number in addition to a non-public IPv4 number I am using. IPv6 has enough IP numbers for everyone to have a public IP. That would fix the port forwarding problem but most everything is still on IP4. Can any talk about when and if we will get the port forward problem solved? Is there a way to use T-Mobile IPv6 number now? Thank
