Most likely this will also blank out video from the UHD 630. The iGPU on 9th Gen Core CPUs is quite difficult to configure. If a discrete GPU (AMD RX or Vega) is used, then both 0x3E920003 and 0x3E9B0007 will work fine, allowing the iGPU to be fully accelerated but with no display output. When the accelerated AppleIntelFramebuffer attaches to this iGPU, it seems to disable video output, but when the default framebuffer attaches, we get video output, but it's not accelerated.
The more you know! I guess I didn't notice because i'm running my iGPU in headless mode for QuickSync.
