Unable to change Hardware Reserved memory for integrated AMD GPU

[Jehov]

I recently bought an HP Pavilion 15-ec0043ax which has an 'advertised' 8GB of DDR4 RAM. But upon opening Task Manager I was disappointed to see 2.1 GB of Hardware reserved memory, which is a shame since all that reserved RAM is going waste, considering the fact that I have a Dedicated Nvidia GTX 1650 GPU with 4GB of Dedicated VRAM and the integrated GPU can run well enough on just 512 MB of RAM.

So far I've seen countless number of posts in the HP community with this same issue and no results provided by HP.

There should be an option in the BIOS, BUT apparently HP has locked the Advanced BIOS settings (I think)for some reason and there's no other way (that works) to fix this issue unlike with other laptop manufacturers. 
I saw a post from a fellow community member (I'll try to link it if possible, EDIT: linked below) which stated that "AMD allows the reduction of reserved memory for the integrated graphics, but it has to be adjusted in the BIOS, which is under the control of the laptop manufacturer".

PLEASE fix this HP, or at least give us a way to access the Advanced Bios OR release an Update/Application that can help us deal with this. We don't need parenting on the usage and modification of OUR devices which WE have BOUGHT.

I'd also like it if anyone comes up with a solution to this and shares it for everyone!

Regards
