Unlocking my laptop BIOS/enabling access to overclocking settings

[kDmD]

Hello, HP Community, 

The other day, I discovered that my laptop's integrated GPU seems to have a fair bit of unused VRAM just laying around that I want to utilize for both gaming and work purposes (I work with Unity and Unreal 4). However, upon digging through the BIOS of my laptop, I found I don't have access to any sort of "overclock" settings whatsoever. 

Is there a possible fix to this? Do I need to login to the BIOS with an admin password (which i don't have) to access these features, or are they just not an available set of options period?

Thank you in advance. 

BIOS version in case it's needed: HP L72 Ver. 01.47

Overclocking can be dangerous if you are not 100% sure what you are doing. It can lead to overheating and ultimately fry your system.

If you can't overclock in BIOS, download Throttlestop. Google it first.

P.S The option is not in my BIOS either.

I know what I am doing, thankfully, otherwise I would not be trying anything to begin with (I'm not trying to mess with my voltage for now, I still mainly just want that extra VRAM). I downloaded Throttlestop and tried running it, but it gave me a popup message that said "CPU not supported" so it seems I can't use that. 

If anyone else has other suggestions please let me know. I am open to downloading a compatible alternate BIOS if someone knows of one if all else fails.
