PCI passthrough UEFI VM not boot with 8 cards

I trying to get PCI passthrough work with my gpu pve servers:
UEFI boot with less than 8 Nvidia RTX 3090, win10 and ubuntu 22.04 is boot fine without any issue; but won't boot for 8 cards, not booting from disk(can not find bootable disk), both win10 and ubuntu.

I tried:

1. Turn off security boot from for guest vm during starting vm
2. Switch Display mode: Standard VGA, SPICE, VirtIO-GPU

I assume RTX 3090 is support UEFI, because 7 cards or less working fine.

I tested seabios...
