Trying to update to High Sierra, missing firmware partition.

[DonutHands]

Running 10.12.6, trying to update to High Sierra 10.3.4

Download and run installer from app store. Boot disk is greyed out and when hovering over I get the message
"You may not install to this volume because it is missing a firmware partition."

Not sure what to do here. Only troubleshooting I did was to run Multibeast 10.2 with "Clover UEFI Boot Mode" checked.

You might try updating your SMBIOS information in your config.plist using Clover Configurator.
Also update Clover.

SMBIOS is filled in with iMac 14,2 info. Clover gets updated through Multibeast, no?

SMBIOS is filled in with iMac 14,2 info.

I think that you misunderstand.
You should update the information that is there to that which is current by using the latest Clover Configurator.

Clover gets updated through Multibeast, no?

No.

Attach your config.plist

In fact copy your entire EFI folder (and contents) to the desktop.
Then delete the Themes folder.
Then right click and select compress.
Attach the resulting zip file.

Open your EFI folder - The real one not the copy.
Delete IM142_0118_B13_LOCKED.scap from /EFI/APPLE/Firmware/

Restart and try the update again.
