No, it’s basically just the drive info grub will show you that you need to add to rEFInd.
When you boot and are asked for a password, it says something like
Enter passphrase for hd0,gpt2 (UUID of that device) :
The info “drive 0, partition 2” (/dev/sda2/) should point you in the right direction.
[EDIT]
Maybe check this old post for some pointers.
