HP Elitebook 8770w Bios modding

[Linuxwindows]

Can anyone help me mod an HP Elitebook 8770w to unlock its integrated graphics? I want to use them for a process that my AMD card cannot do. Also, can I also get help with modifying that card to have a better core and memory clocks?

Overclocking a laptop isn't a good idea. They barely cool the chip and GPU at stock, nonetheless overclocking them.

The BIOS should allow you to enable the integrated GPU, no?
