Don't know for sure. Haven't really examined grubby (it is a binary),
but checking for files it may look at reveals this list:

root@prophead ~]# strings /usr/sbin/grubby | grep "^/" | uniq

So based on that, no it doesn't look at /etc/default/grub. However,
grub2-mkconfig does seem to consult it. I suppose you could remove it
from both /boot/efi/EFI/fedora/grub.cfg AND /etc/default/grub.
