As far as I know, inbound TCP/UDP connections are not supported on Starlink natively. You can of course use a VPN or various types of reverse port forwarding.
That said, you can often still communicate between two NATs using various traversal techniques, although that's generally less likely for carrier-grade NATs, so NAT traversal solutions usually need relays as a fallback anyway.
