How would this differ from NO_GFX_INIT (src/device/Kconfig)?
this config to skip only GT programming, coreboot can still make use of software rendering to make use of graphics.

This is a setting that usually is expected to be done by the firmware, […]
SOC without GT fused won't be able to program GT register, it will cause hard hang.
