Proxmox ZFS Boot NVMe - DISK_KIND_INTERNAL

[KoeSource]

Hello

Goal

Boot into NVMe(PCIe Adapter) on a Supermicro (UEFI) board.
UEFI BIOS -> SATA SSD (Clover, load NVMe driver) -> NVMe with Proxmox installed (ZFS)

It works out of the box if i install Proxmox with ext4 filesystem.
But i would like to use ZFS

Issue

Can someone please explain to me what the following means?

40:088  0:000        Loader entry created for 'PciRoot(0x0)\Pci(0x2,0x0)\Pci(0x0,0x0)\NVMe(0x1,C4-A9-5B-48-4A-44-1B-00)\HD(2,GPT,A673440C-D427-45CB-A351-2ECA742ECF25,0x800,0x200000)\EFI\BOOT\BOOTX64.efi'
40:088  0:000        Menu entry added at index 1
40:088  0:000       hiding entry because DiskKind is DISK_KIND_INTERNAL: \EFI\BOOT\BOOTX64.efi

I need to boot from this partition, why does it get hidden?
Is it possible to autodetect and show this partition, if so how?
if i use the config_working.txt it works, but i have to edit add the partition GUID.
