Serial LCD - how to suppress "Backlight" message

My application requires quick setting of the background colors on the “SparkFun 20x4 SerLCD - Black on RGB 3.3V LCD-14074” without it posting a “you’ve set the background to x%” message to the screen.

Is there a way to suppress all status messages generated in response to configuration changes (setting number of characters/lines, colors, etc…)?

Does this require tweaking the sketch run on Serial LCD?

I believe there is a firmware update that corrects this. The hookup guide for the display has the link for the updated code.
