help with notebook

Hi, good night everyone.

I have an Dell Inspiron 5310 Outlet notebook but there is one thing I wanted to understand,

it has a Intel Iris Xe video card, but I noticed that it is also using the processor's integrated graphics. An example of this is Minecraft.
Even using optifine I have bad graphics and little performance because the game is using the integrated card instead of the dedicated card.

I use optifine to increase performance and add shaders but it doesn't work as it should.

The shader pack I'm trying to use is this one: https://wminecraft.net/bsl-shaders-mod-shaderpack-for-minecraft/

Thanks in advance for everyone's attention.
