If the Fedora image is fresh enough then there are some patches either

https://sources.debian.org/src/shim/15.7-1/debian/patches/block-grub-sbat3-debian.patch/
You may check changelog, closed debian bugs, messages in developer
mailing lists for the shim package (shim-signed and shim-unsigned) and
may try to discuss the issue with shim maintainers.
