I’ve not tried it, but you can do three EFI partitions on the same drive. There’s no real limit to how many EFI partitions you can have. The key here is to keep Windows and Linux boot files separate at all times. If they share the same EFI, then Windows will undoubtedly break it at some point. Having refind as the default just makes it easier to choose which OS you want. Rather than relying on Windows Boot Manager or Grub. Of course to do all this you need to wipe the disk to set up the layout.
