Hi,
I'm wondering how to change the default baudrate of the "SparkFun 20x4 SerLCD - RGB Backlight (Qwiic)" display to another value.

I know the default is 9600 but I want to change it to something like 115200 so that my Raspberry Pi Zero 2 W can talk to it much faster.

As it stands now the Pi's I2C bus speed is set to 9600 to avoid communications issues between the display and the Pi which was a previous problem for me as the default on the Pi is apparently 100000.

Is this possible on a Raspberry Pi at all?

EDIT:
Could I with the command() function send the appropriate value as shown in this table under "Configuration & Command Set"?:
