I remember to have seen discussions about newly installed shim adding
names of older shims or bootloaders to something called SBAT.
I find in my mailbox a mail with a link to
  https://bugzilla.opensuse.org/show_bug.cgi?id=1209985

About SBAT i found in the web:
  https://www.gnu.org/software/grub/manual/grub/html_node/Secure-Boot-Advanced-Targeting.html
  https://github.com/rhboot/shim/blob/main/SBAT.md


Have a nice day :)
