Like so:
# grep PROB /etc/default/grub
#GRUB_DISABLE_OS_PROBER="false"
or like so:
# grep PROB /etc/default/grub
GRUB_DISABLE_OS_PROBER="false"
If it's like the first, then /etc/default/grub has not changed the
default from true to false. Don't forget, simply editing that file
doesn't change anything. Regeneration of grub.cfg is required to
incorporate that any change within that file, either manually, or
by a kernel installation or removal, or possibly regeneration of an
initrd.
Your non-English command output, coupled with forced line wrapping
of long lines makes it frustrating to try to assimilate your data
provision. Commands need to be prefaced with something like "LANG=C"
to cause output in English for sharing in an English environment like
this mailing list. Pastes need to kept from forced wraps, so that the
reading window stands a chance to show one line of source on only one
line in mail reader, or copied and pasted elsewhere where wrapping is
not forced.
An option to pasting command I/O into an email subject to format
corruption is to use a pastebin service, such as susepaste in TW
or fpaste in Fedora, to upload this information for viewing in a
web browser via URLs provided to you by the pastebin service used.
You may compare your commands to some of the same on one of mine.

7-27 + 30 each have installed distro, which could be a pretty
big "mess" in NVRAM or autogenerated boot menus with os-prober
enabled. I make all my own boot stanzas in /boot/grub2/custom.cfg
on the TW installation, which TW's Grub presents at boot before
any autogenerated entries, due to the use of /etc/grub.d/'s
41_custom copied to 07_custom, with 41_custom zero'd to prevent
presenting all those same entries again after the list of
autogenerated entries.

The template I use is:
efibootmgr -c -L "opensusetw" -d /dev/nvme0n1 -l
'\EFI\opensusetw\grubx64.efi'
That string you tried for -L I would expect may be an excessive length for
the NVRAM to use in its entirety. I've never had reason to try anything
that long. In my UEFI BIOS it reads simply opensusetw. Also, I match it
to the ESP directory name:
# grep DISTR /etc/default/grub
GRUB_DISTRIBUTOR="opensusetw"
#

You haven't shown where Fedora put its kernels or initrds. Are they
in /boot/, or on the ESP. I can't be sure from your wrapped non-English
data whether all share a single ESP. All my Fedora kernels are in /boot/
on their / filesystems. I think this is what you have too, in which case
I'm puzzled why os-prober doesn't seem to have done its job correctly
for you. Still, I don't like seeing two Fedora efibootmgr entries. One
would seem to be leftover from its first installation, and same for TW.
I would also remove the Debian entry if Debian is no longer installed
anywhere.
