Shorter menu titles in grub2

I would like to make the menu titles of grub2 shorter for them to fit in my theme. Namely, Fedora 38 rescue instead of Fedora Linux (0-rescue-7ad84fe099814e3388129347d2a46891) 38 (KDE Plasma) and Fedora 38 (6.2.13-300) instead of Fedora Linux (6.2.13-300.fc38.x86_64) 38 (KDE Plasma) If I am not mistaken, I should need to edit by hand the file /etc/grub.d/10_linux, which is not a trivial task. And, more importantly, this file will be changed by an update of grub2-tools package. This is not practical, I want a 'maintenance free' thing. Is there any way to configure a different grub2 menu title in a persistent way? I use the 40_custom file for my menu entries, but the kernel entries are handled automatically.
