I have confirmed the tweak posted by @vimb. Disabling VT-d in the BIOS allowed me to install TrueNAS SCALE. I was able to easily upgrade my previous CORE installation. I can also confirm the built-in Aquantia ethernet device works fine with Linux drivers. I did not see any PCIe errors, so I did not add the pcie_aspm=off parameter. Thank you for your experimentation and for posting here on the forums!
Now all can use the TerraMaster F8 SSD (Plus) without worry 
, at least as long as they don’t need hardware passthrough for their VMs.
I am unable to edit my original post, however I did mark the reply with the tweak as the “Solution” to this thread as recommended by @etorix.
Here is the new list of required BIOS changes for SCALE:
- Security → Secure Boot → Secure Boot → Disabled
- Required to boot TrueNAS SCALE
- Chipset → North Bridge → VT-d → Disabled
- Required to boot TrueNAS SCALE
- Boot → TOS Boot First → Disabled
- Required to enable editing the boot order
And optional kernel command-line tweaks for SCALE:
pcie_aspm=off- Reduces PCIe errors reported in console.
