disable hybrid graphics on a laptop - intel integrated graphics only


I own a HP Laptop with an integrated Intel graphic card and a dedicated AMD Fire Pro graphic card. When I boot into my system - it always uses the dedicated AMD graphic card which needs a lot of power. I therfore like to disable the AMD graphic card and would like to use the Intel integrated graphics only (like in Ubuntu or Debian).

Here is the output of inxi:

Can anyone help me?

Many thanks in advance and stay healthy.

The best way is to disable it with BIOS settings.
