Recent Fedora installs use drop-in files unter /boot/loader/entries
instread of adding menu entries to grub.cfg directly.

For example on my Fedora I see this:

# ls /boot/loader/entries
74d1214a68a2411c9641304cc418fd37-0-rescue.conf
74d1214a68a2411c9641304cc418fd37-6.2.10-300.fc38.x86_64.conf
74d1214a68a2411c9641304cc418fd37-6.2.13-300.fc38.x86_64.conf
74d1214a68a2411c9641304cc418fd37-6.2.8-300.fc38.x86_64.conf
