The limiting factor here is a hardware limitation; Nest Wifi Pro has 1 GB ethernet ports so no there is no way to make it faster. If you want to be able to make better use of your 2 GB internet plan, you will need to look at a different mesh solution that has 2 GB+ ethernet ports (typically 2.5 GB ports from what I've seen).
It's also important for you to know that Nest Wifi Pro (and other similar mesh solutions) support Wi-Fi 6E (AXE5400 or AXE4200 outside of the US), meaning it's theoretically capable of up to 5,400 megabits per second (Mbps) of combined data flows through your router (4,200 megabits per second (Mbps) outside of the US). I emphasised theoretically as that's a theoretical maximum, meaning you will realistically never get that speed aside from in absolute perfect ideal conditions. That's because your actual speeds depend on your Internet Service Provider, network conditions, capability of connected devices, local regulations, and environmental factors such as building construction and wireless interference.
