Should I disabled my Intel integrated graphics?

So, the reason why I want to disable it, is that I use Adobe Illustrator nearly everyday, and there is a setting for GPU Performance. Sometimes it is enabled and sometimes it isn't. I think the reason behind this is because I think that Illustrator gets confused with the use of 2 GPU's. As I am also using a Nvidia GeForce GTX 965M (4GB VRAM) too.

I would like to know if there will be consequences or changes if I disable the integrated graphics. Like, will there be a slight performance change etc. The integrated graphics is Intel HD Graphics 530.

Thanks
