Can I disable AMD Vega 8 GPU on a Laptop?

[Xengri]

I bought an Asus laptop which came with a Ryzen 5 2500U and a GTX1050 with 8GB RAM, I want to know if I can disable de Vega 8 integrated graphics in the Ryzen CPU since it does nothing but use RAM. Also, I would like to know if it could be done the other way, can I disable the GTX 1050? I would like to do it because it would improve battery life when I'm doing lite work on the go as the Vega GPU is enough for that and I don't need the RAM. If not, I would like to know how to disable the Vega 8 and get the 2GB out of 8GB of RAM it is using free. I won't be using 2 GPU's at once so I want to know if I can disable either of them.

If your laptop is working properly, the Vega 8 or 1050 will automatically switch depending on the task. For gaming it'll use the 1050 and for light web browsing it'll use Vega, no need for you to disable anything.

You probably can specifically define the game in Nvidia Control Panel

The main thing I would like to do is to get those 2GB of RAM free, battery life, after all, won't improve that much, but I want the 2GB of RAM back, I thought that disabling the Vega 8 would do the trick.

Start the laptop with F2 pressed and you should enter BIOS, there you could look for the iGPU framebuffer setting at 2G and lower it to 128MB?

the BIOS on the laptop is so simple it doesn't offer anything apart from boot order and some usb and sata settings

Your battery life would get considerably worse disabling the iGPU, so uh... It kinda defeats the purpose of a laptop...

Well, I think I will just let it as it is, getting 1GB of RAM won't do much anyways, I am better of just using the iGPU and disabling the dedicated graphics.

Hi guys, i've got this same problem. My laptop specification is 
Acer Nitro 5 AN515-43
AMD Ryzen 5 3550H Processor
Nvidia GeForce GTX 1650 Graphics
8GB RAM
I bought this laptop October 2020. I already configured the settings in Nvidia Control Panel and also in Windows Graphics Settings to use GTX 1650 in high performance. If I start to play Valorant(other games too), I'll get 100 fps but after sometimes it will drop to 20 fps and even lesser to 4 fps at CPU temp at 96 C; GPU temp at 70 C. I never ran any other programs while playing. I came to know that, in Task Manager it is showing GPU 0: Nvidia GTX and GPU 1: AMD Radeon. Is there a way to change? Ive also tried changing the global settings in high-performance Nvidia processor and also changed in program settings to high performance. 
Is there a way to put my dedicated GPU to GPU 1? and how to get stable fps?
Is there a way, so i can play better
