On a new Dell XP 13 I had for a bit in January, it had two F keys to
use. One was for setup which is where the boot order could be
permanently changed. Another one was for just one-time boot and was
not persistent. So you'd need to dig around to find an option to make
it  persistent. Or you can do this from within Fedora using
efibootmgr. So you'd do:

efibootmgr -v
And then you'll see a BootOrder, and you can man efibootmgr to find
the proper flag for changing the boot order, and make Fedora first in
the list. But before you do that...

Clear+reset the terminal window. Then do:
bash -x grub2-mkconfig

Copy-paste the entire window results into a (gedit) text doc and post
a URL for us to take a look at it; it won't fit in the mail list. And
also post the contents of /etc/default/grub - this will fit in the
mail list.
