I don't think grub2-install or grub2-mkconfig are calling for a USB driver to be loaded by default. It's relatively recent code, maybe a couple years at the most? What's increasingly happening on UEFI systems is that USB isn't being initialized, in favor of faster boot times. This means you can't get to the firmware's configuration menu either. The way this is expected to be done, is executing a user space application to enable setup mode on the next boot.

For now, longer is better. Diceware is recommending 6 word passphrases.
