Help on getting Brightness Control on GTX 1070 Laptop Hackintosh (High Sierra, no iGPU)

I tried using AppleBacklightFixup (with the aml) and some other posts that related to similar issue about this in InsanelyMac, but none of those have fixed my issue of having 100% brightness with no control over. (yes my eyes are straining.)

  • i7-7700HQ
  • GeForce GTX 1070 (no iGPU)
  • 10.13.6 High Sierra
  • Realtek USB Wi-Fi Device & Intel AC8265
  • 16GB RAM
  • Realtek ALC899
  • P650HS-G or NP8157

Is it possible to add backlight feature on this Hackintosh Laptop? More info given on any request.
