When I encountered this issue a few years ago, the answer was that it
is only possible to have a single Fedora instance at a time using
grub.  What you describe above, two UEFI boots for Fedora showed up in
the menu, is an anomaly. It should not be possible. When I want to
boot a different EFI partition, I have to go into the bios boot menu and
select the different efi partition. That is, only one efi partition can
be active at any one time.  There is an exception to this,
systemd-boot, which finesses the issue by putting all efi candidates in
a single partition, as I understand it. But it doesn't sound like you
are using that if you are getting a grub menu.

Since your system seems to be exceptional, you could try running 
grub2-mkconfig, which runs a discovery program, and maybe it will add
the entries correctly to your grub menu.  For F33, I think that is still
grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
for efi.

In F34, the grub.cfg file is now in /boot/grub2/grub.cfg for both bios
and efi.

I think the answer to your question is to use the bios boot menu to
select the SSD version as the default Fedora boot.  Or at least move it
above the HD version.
