I would need a USB<->UART converter and do some soldering, then fix the bootloader to re-enable the USB-C...

meh.

I mean, you'd need to solder headers onto the board, but otherwise not really. There's JTAG headers pre-soldered that might work too, but I'd have to look at which UART/CPU they're hooked up to.

You don't need to solder anything.

The UART GPIOs are wired to a board standard connector? If so I would need that USB(connector)-UART(connector) cable I guess.
