You could actually just disable IGPU without changing your SM and have DRM work. You only really need to change the SM to iMacPro 1,1 if you want HEVC hardware encode/decode. I mean it has been a long while since I messed with that stuff but if I remember correctly when I was first getting started I was tinkering with no IGPU and it seemed that DRM stuff worked only when IGPU was disabled.The only way I found to fix DRM was to disable integrated graphics and change smbios to iMacPro 1,1 after doing that Apple TV and whatnot works.
