No, you should edit it to be something like “Boot with standard options” “ro root=UUID=96e2ea68-742d-4309-ae9f-4d12ba668b21 quiet splash” mine says /dev/nvme0n1p4 because that means device (/dev/) first nvme SSD controller (nvme0) disk number 1 (n1) partition 4 (p4). If yours worked with that line you copied from mine it’s only because coincidentally your / partition is the fourth partition on the first nvme SSD on your computer. (Or maybe because that config is not being used).
A question though, why do you want to use refind if you don’t know the basic about partitions and boot drives? I think you’d had a better experience using the default one which is GRUB.
