HP 15-g054nl Request InsydeH20

Hi guys, i'm sorry to disturb you, but i need your help.

I've bought an HP 15-g054nl with AMD R5 Integrated and Dedicated AMD Radeon 8570M

I'd want to disable the integrated one from bios due i've found no way to do it via software

But the BIOS is locked, i tried to access to the bios with A + F10 but seems not working, can anyone help me?

Thank you a lot
