Multiple (most?) motherboard manufacturers have options to install drivers and software from the BIOS. So you don’t have to go download it elsewhere just to get your system up and running.

That setting can be turned off. In fact they usually turn themselves off after the first boot because otherwise it would prompt every time.

But, you’re referencing Lenovo, a full system integrator, not a separate hardware company. Of course the system integrators bundle shit, that’s not new at all. They’ve done that for decades.
