how to disable “intel display power saving technology”

I’m using a Dell Vostro 5490 running Windows 10. Under “display adapters,” for me it says

Intel(R) UHD Graphics 
NVIDIA GeForce MX250

I tried disabling the Intel Display Power Saving Technology, because the automatic foreground/background screen brightness adjustment is annoying. But I can’t seem to find the option listed on most guides. There is no Display Power Saving Technology checkbox. There isn’t even an Enable adaptive brightness setting in my power options.

In the Intel Graphics Command Center

No Enable adaptive brightness setting
