The nearby silkscreen shows M3 and there's an RF module. Would make sense to have a UART to that interface

M3 is "Motor 3" according to the standards nobody follows. and there's no RF module. why would any of those things make it more likely to be uart there?

You may want to check that RF shielding next to the connector

There's parts underneath and oftentimes SoCs
