No "Adjust keyboard brightness" after update

Hi nishant_kp,

If you haven't already, you should check Turn your Mac keyboard’s backlighting on or off

"Manually adjust keyboard backlighting or turn it off

Do one of the following, depending on your Mac model:

• On the keyboard, press the increase brightness key  or the decrease brightness key . To turn backlighting off, keep pressing .
• In Control Center, click Keyboard Brightness, then drag the slider.
• In the Touch Bar, expand the Control Strip, then tap the increase brightness button  or the decrease brightness button . To turn backlighting off, touch and hold .

Automatically adjust backlighting in low light conditions

1. Choose Apple menu  > System Preferences, click Keyboard , then click Keyboard.
2. Select “Adjust keyboard brightness in low light.”

Automatically turn backlighting off after a period of inactivity

1. Choose Apple menu  > System Preferences, click Keyboard , then click Keyboard.
2. Select “Turn keyboard backlight off after [time period] of inactivity,” then choose a time from the pop-up menu.

Tip: The light sensor is located at the top of your computer near the camera; make sure that area isn’t covered when you use your Mac in low light conditions."

Cheers!
