Discrete graphics switched off in BIOS.
lspci | grep VGA shows no indication of the discrete graphics. Is this enough? Or are there some additional steps to be undertaken? Like this for example?

Turning it off in the BIOS should do the trick, but you're worried if it is still sipping power, right? It should not, but I don't know how to confirm this.

If you can turn it off in the BIOS, that should be sufficient. The Arch wiki seems to be talking about cases where the BIOS doesn't offer that. Since you _have_ switched it off in BIOS, you should be all set.

(I recently discovered that the video out on my Thinkpad W530 only works with the discrete graphics, thus tossing me into a journey of pain I had happily been avoiding by using the perfectly-good integrated graphics.)
