Starlink doesn't offer static IPs. You can get a public-facing IP, but it is still DHCP and subject to rotation. However, the official response from Starlink is that it rarely changes (even during reboots/firmware upgrades). It basically functions as a static IP, but they reserve the right to change it for network reconfiguration at their benefit.
You can now get a Starlink "enterprise kit" that is the standard dish without the router. It includes a power supply and longer cable for $799 if I'm not mistaken.
