I removed the entry from my grub2-efi.cfg and it never came back until
I realized that I hadn't removed the rescue stuff from /boot. if you
have an old rescue kernel and initramfs it won't make a new one. 

Removing those and installing a new kernel did make it work. 

So, to cleanly remove it: 

* remove the grub2* entry
* rm the stuff from /boot
* dnf remove dracut-config-rescue
