found mention of grub command nativedisk which I added.
I don't know anything about nativedisk or the distinctions between
various types of driver.

I have tried the nativedisk command on a laptop configured to boot using
UEFI. With default efidisk, ls reports hd0, hd1, hd2. After nativedisk
they become usb0, ahci0, ahci1. When a USB stick is not inserted, hd0 is
an internal hard drive. It seems nativedisk allows to make smaller a
chance to use a wrong drive. Search for a specific UUID should be even
more reliable.
I agree that nativedisk description in the GRUB manual is obscure.
In my case there is "Fast boot" config option in the firmware setup. It
should be disabled to reliably boot from USB.
