Is there anyway I can control keyboard's backlight? In Windows 10 in general or for my Dell Latitude 7290 in particular?

My Dell has a great keyboard's backlight feature, but it turns it off after only 10 seconds since last key is pressed.

10-15 seconds is by far too short for me. It causes a terrible eye discomfort, when using computer in darkness. If only I pause typing for a short moment, everything goes black. And once I resume typing, I am hit with lights.

I cannot verify this right now, but I am pretty much sure that my Lenovo notebook turns off keyboard backlight after at least 30 seconds, if not 60 seconds after last key was pressed. And such eye effect / problem does not occur.

My current research:

1. I cannot control this via keyboard's hardware -- Fn+F10 only controls whether backlight is turned off or the level of intensity, but not the auto-turn off timer.
2. I found nothing in Windows 10's keyboard configuration corresponding to backlight.
3. I have no Dell-related software installed on my laptop. If fact, the only Dell-related software that I can find when I type "Dell" in Start Menu is Dell Command Update that, again, has nothing either for backlight of keyboard or for the laptop configuration in general -- it only updates drivers.

Is there any way I can control this?
