That warning says installing Intel's driver will remove Dell customizations. That means you should not ever install Intel's drivers. Dell customizes all drivers to work on the Dell laptop motherboard. All updates should come from Dell. Sign up at Dell to get any notices for updates from Dell. Dell updates for laptops are rare.

Yes the part at the top says it will remove, but then lower down it says if your processor is 6th Gen or higher, the customisations will remain.

I'm going to try this on my Dell Vostro 5593. Currently when using MS Teams Video calling, through the Intel GPU, my cameras (built-in or 3rd party camera), both makes my video feed jerk/jump, however when I change MS Teams App to use my built-in NVidia MX GPU chip, the issue goes away. 

Laptop did not explode after updating with the Intel Driver, but the issue remains.
