EDIT: never mind, right after I posted this I found it under another disk identifier.
I have High Sierra installed and running but forgot to copy the apfs.efi to my EFI folder on my Sierra boot SSD where Clover is installed in the EFI partition. I able to boot using a USB stick with Clover installed but now that I am in High Sierra I do not see where clover is installed any more since there doesn't appear to be an EFI partition on my now AFPS drive. However, if I remove the USB stick and try to boot normally, Clover still pops up so it is there somewhere on the drive.
Here is a screenshot of the AFPS volumes:
