Yes, and I mentioned that earlier. A rEFInd flash drive has its own EFI partition, though, so works without one on the main drive.You will need an EFI System Partition (ESP) for UEFI boot for starters.
Indeed, the usual use of a rEFInd flash drive is system rescue in the scenario where the main EFI partition has stopped working (e.g., due to Grub or NVRAM error).
