OK, I have 5.8.14
In the xz ,, in /usr/share/libalpm/90-linux.hook
(linux-5.8.14-1-aarch64.pkg.tar.xz)
is the line,,,, Exec = /usr/bin/mkinitcpio -p linux
-p means that you should look in /etc/mkinitcpio.d for a file linux,,
and maybe edit it
BTW, in 5.8.14 panel-simple is builtin, not a module
I don't know about 5.7
-----
and check /etc/mkinitrdcpio.conf,,, also its man page
