The English doesn't (quite work), but Intel here refers to the integrated, power-thrifty GPU, so could be more pedantically stated as "run on integrated graphics chip and turn off the Nvidia discrete GPU (and save power)" instead.
fragmede is saying that when aero-glide2 said "Intel" they were actually referring to the integrated GPU in the laptop in general. Of course there's no integrated Intel GPU in the Ryzen 9 4900 HS, but there is an integrated GPU (a Vega 8).
