How i can change from APU to GPU on the notebook? How i can toggle Advanced Settings in BIOS?

[Avicona]

Notebook specs:

CPU: AMD Radeon A10-4600M APU 2.3 GHz

Videocards: AMD HD 7670M 2GB (GPU) and AMD HD 7660G 512MB (APU)
RAM: 8GB

OS: Windows 10 Home

BIOS: InsydeH20 F.21

Question: How can i change from AMD HD 7660 G to AMD HD 7670M without Catalyst (because Catalyst is not help to change videocard, there works only AMD HD 7660G or both video cards with Dual Graphics, but i need to AMD HD7670M only)?

Maybe i can change it from BIOS? But i should turn on Advanced Settings in BIOS. 

How i can turn on Advanced Settings in BIOS? 

I  tried to update BIOS by pressing Win+b/Win+v while notebook is starting but nothing happened. There was a black screen.

I read different topics on forum but it doesn't helped.

My English is very bad, I was trying to explain the whole problem.

You cannot permanently apply the dedicated video card. There is no setting in the BIOS or Catalyst to do that. The system is going to prefer to use the APU card except for specific apps you set to run on the higher powered video with Catalyst.

Thanks for the reply. But for the future, how can I enable advanced settings in BIOS? 
My BIOS - InsydeH20 F.21.

You cannot. There are no hidden advanced settings in the BIOS. What you see is what you get as barebones as it is.
