How to install Intel HD Graphics driver on 20.04?

I have 2 GPUs: Intel HD Graphics 620 and NVIDIA GeForce 930MX Ubuntu has automatically installed the proprietary driver for the NVIDIA GPU. But, I can't see the Intel HD Graphics GPU in update manager. I think that everything on my laptop is using the NVIDIA card, wich is causing it to overheat when I don't have any applications open.

Here is the output of sudo intel_gpu_top:

It seems like Ubuntu is not using the Intel GPU.

Is there a way to install a driver for Intel HD Graphics 620?

The Intel Graphics driver's preinstalled in the kernel.

https://www.linuxbabe.com/desktop-linux/switch-intel-nvidia-graphics-card-ubuntu shows sudo prime-select intel switches back to Intel and prime-select query shows which card is active.
