How to disable onboard graphics.

[techno43]

Hello.
I have dedicated amd hd7670m and integrated hd 4000 videocard.Is it possible and how I can disable my hd4000 or how i can at least enable option to control switchable graphics mode (fixed or dynamic)?Because i dont have this option in bios.Also is there any difference in perfomance between this modes?Currently i have this bios version:Insyde F.25,5/29/2013.My os win 8.1 pro.On hp page with drivers i found newer bios version:F.27 Rev.A(it will help?).Is there another solution apart update my bios for example can i  flash modded version of my bios?
Thank you in advance

Switching between adapters is dynamic per posted HP documentation. Therefore this is no need to disable anything.
