Lenovo Y50 UHD Bios Unlock

Hello, I am new to this forums, and came here to ask for help, recently i am trying to set my graphic device to be using Dedicated graphic card (GTX 860M), (I am not doing it for gaming but for other purposes), to do that, a friend of mine told me i had to unlock my bios. and am really dumb when it come to this bios stuff, and i'm also afraid of risking destroying my laptop.

I used CMD to get to know my bios version (Using the command "wmic bios get smbiosbiosversion")

And it is: 9ECN43WW (v3.03)

Appreciate any help!
