B550 tomahawk how to select boot gpu

[sneindor126d02a7]

Hello, I have a system with two gpus one for the main OS and one for hardware passthrough.
I cannot find the option to select which gpu is the boot gpu, but default it boots the main x16 slot, however I want it to boot from the secondary slot.
I previously had a gigabyte b350 board and this was a simple setting

I’m hoping it’s something I’ve missed and not a limitation of the board.
Thanks in advance

Think you can only set between PEG and IGD and not from PEG places.

but default it boots the main x16 slot, however I want it to boot from the secondary slot.

You can try connect the display to the 2nd card placed in 2nd PCI-E slot,
else reverse the places of the GPUs
