Well try out bootctl remove and remove any kernel images in your /boot or /efi directory .
After which, run sudo pacman -R kernel-install-for-dracut , after which , run yay -S dracut-hook && linux linux-headers followed by running refind-install
.Reboot and see if the system boots and shows EOS as an option.rEFInd’s autodetect should detect the files.
Please paste out the part of your refind.conf which specifies the boot entry and initramfs files . I think I might be able help you.
EDIT:This works , just tried it on my host system.
