If you have network boot enabled and you’re on a recent enough uefi you’re vulnerable yes. However personal devices have uefi network boot disabled by default
I swear I have seen plenty of PCs attempt a PXE boot before failing and continuing on to the next boot option. It probably isn't the default for most "personal" machines but... That's not really a guarantee I would want to hang my hat on...
