Yes, it's literally just
Serial1.setup(115200)that you need. Then you can connect to the IDE at 115200 baud using the B6/B7 pins and a USB-TTL converter.However are you connected via USB? If so, the console on USB ignored the baud rate and is already running as fast as possible over the USB connection - it should be way faster than 115200 baud.
