in the command you gave me,

sudo grub2-editenv - set "saved_entry=133a2487cda040dbbe9609f0ab827def-5.10.20-200.fc33.x86

the entry x64 is absent. Is it normal, is it supposed to be like that?

FWIW, I decided to test on a system here what would happen with a bogus entry.

My system was booted to the 5.10.20-200 kernel and I gave a bogus entry....

[root@f33k ~]# grub2-editenv list
saved_entry=8b511c4b483b4414b7bf742b35809e2c-5.10.19-200.fc33.x86
boot_success=0
boot_indeterminate=0

I then rebooted the system. The entry above remained unchanged but the system again
booted to the 5.10.20-200 kernel.

So, the good news is that I'd probably wouldn't be responsible for breaking your system. The bad
news is that the results would have probably confused the issue even more.
