How to enable brightness function keys on Dell Latitude 7450 with Intel HD Graphics 5500?

Brightness function keys appear to be disabled on my Dell Latitude E7450 with Intel HD Graphics 5500.

Latest drivers installed.

I can change the brightness through the intel console, but not through any windows control such as power menu.

I presume it is being managed by the Intel App? How do I disable that?

Thanks,

Please bear in mind that you have loaded Intel® generic graphics drivers, they may or may not provide you with all graphics features that are integrated on your computer model.

 

In fact, if you would like to use or disable brightness features, you need to check with your computer manufacturer for customized drivers that will fit your computer model.

 

The Intel® graphics driver does not offer an option to disable brightness control.
