Disable amber light above trackpad

I have a Dell Inspiron R15 that I bought four years ago. Upgraded to Windows 10. 

This  afternoon I come home and I see a message that Windows has installed some updates. I now notice this annoying amber light above my trackpad. I've never seen this light on before, wasn't even aware it was there. 

Looking it up, apparently this light is on to let you know that the Dell trackpad driver is installed and the trackpad is activated. This is weird, because this light has never been on ever, and my trackpad has always worked. Docs say to use FN-F3 to turn the light off, which also turns off the trackpad. 

This is annoying. 

I looked through this new driver functionality and it has a bunch of nifty options and gestures that I will never use. So I'd like to be rid of all of this and go back to my perfectly functioning trackpad without annoying amber light distracting me while I work. Except when I try to uninstall it I get an error message that the specified module could not be found. 

So how do I set this back to the way it was this morning?
