Windows 10: Increase VRAM on Bootcamp-ed Mac

My computer uses Intel Iris Plus Graphics 640 and says my total graphics memory is 4156MB

and dedicated vram is 128, I want to increase this but I am on a mac running windows, also known as bootcamp. I cannot run BIOS because my motherboard only supports UEFI, but when I go into advanced options, it does not show to boot to UEFI, is there a way to fix it or increase my VRAM another way? I have tried regedit and many others, please let me know.



Thanks in advance.

Accessing BIOS in Windows 10 That Has Been Bootcamp-ed From Mac OS

Hi, i'm relatively new to Windows 10, can anyone help me on this ?

I've searched that there is only 2 ways that you could *actually* increase your VRAM or Dedicated Video Memory, and that is by :

1. accessing to BIOS

2. buying a new Graphic Card

and 3. via Regedit (in which I said there's only 2 ways that *actually* increase the VRAM, and this one doesn't, as far as I know)

but the thing is, my PC has been bootcamp-ed, that means, i'm using iMac but the OS is Windows 10.

Also, I can't access my OS X(Mac OS) anymore due to my error deleting its data and stuff.. so yes, i'm stuck using Windows 10, but that's beside the problem.

I have 2 x 4 GB of RAM, and would want to increase it to somewhat 1052 ? as suggested in some video I've watched (I think, cause' I can't really recall what the number suggested was)

and by this, I need to access BIOS, but the thing is, Mac uses something called Open Firmware and now, due to me having Windows 10 right now, I can't press the suggested key (when restarting) because i'm not using Mac OS!

is there anyone that could perhaps help me In some way to access BIOS?

one more thing, I've followed the UEFI way(The one in the Recovery setting), and tried to disable fast startup to make it possible to access it, and the result was nada. (It didn't show up, and some article said that It could be that my PC didn't support UEFI
or something in the first place)

Side Note:

- You could ask me for my PC spec (though please tell me where I could see it, cause' i'm pretty new to Windows 10) and i'll give it to yah

- I'm sorry if my post was in a wrong category, I don't really know which category this should fall in.. thanks for reading though!
