Hi,
i have the same issue but I cannot solve it.
I have a consumer motherboard (Asus H87 PLUS) with secure boot which do not le me boot from my FreeNAS 11.2 USB drive created with Rufus.
It is for sure my motherboard the issue.
Would anybody help please ?

I was finally able to SOLVE it.
Issue Description
Cannot boot from USB (SANDISK 16GB) with flashed FreeNAS 11.2 U7 on ASUS motherboard H87Plus
Introduction
I have no CD ROM on my home NAS so the only option was to use an USB as installation media.
I change my BIOS configuration dozen of times between :
- secure boot : Windows / Other OS
- CSM
- Boot dev control: UEFI + Legacy / UEFI / Legacy
- Boot storage device: Both, legacy firs / Both, UEFI first / UEFI / Legacy
- Legacy
- UEFI
- And with different USB speed port: USB 3 / USB 2
My final configuration was:
- secure boot : Windows
- CSM
- Boot dev control: UEFI + Legacy
- Boot storage device: Both, UEFI first
- And the USB plugged into USB 3
I flashed the USB drive different times with RUFUS from Windows 10 and with dd from Fedora 31. (Take this in mind!)
Never never never able to boot from that damn USB!
Solution
It was a great stroke of luck.
I saw a strange label on boot when flashing the USB with dd from Fedora.
My USB had a UEFI in the name at the boot prompt.
Sooooo... ?
To have a working boot USB use:
sudo dd if=FreeNAS-11.2-U7.iso of=/dev/sdb bs=64k
This is the only option to have a boot USB supported by my motherboard with Secure Boot!
I leave it to posterity
Namaste
