Is it possible to enable iGPU via UEFI scripting on intel C246 based system?

I have a request that I’m pretty sure is impossible due to Dell’s configuration. I have a Dell T340 with an E-2176G processor that I originally purchased with hopes to use QuickSync. Dell has disabled the iGPU due to their IPMI configuration.
I had given up hope until noticing that the ASRock E3C246D2I does have a method to enable the iGPU.

I’m new to this topic, and I was wondering if there was anyway to configure support for this using the UEFI shell to set the variables required directly?
