how to Gravity: TCS3430 XYZ Tristimulus Filter ALS / Gain settings

Recently bought Gravity: TCS3430 XYZ Tristimulus Filter.
There is no LED and INT pin available like a breakout board.

When switching on the LED, I get a very high gain output. 

X : 36863 Y : 36863 Z : 25412 IR1 : 4530 IR2 : 1519 
X : 36863 Y : 36863 Z : 25249 IR1 : 4505 IR2 : 1510 
X : 36863 Y : 36863 Z : 25224 IR1 : 4501 IR2 : 1502 
X : 36863 Y : 36863 Z : 25250 IR1 : 4507 IR2 : 1505

Is there any option to control the LED gain via the program for this specific board?
I am using aurdino UNO

Thanks in advance.
