I use an HP Z32x via DisplayPort.
I think netkas' tweak is the safest bet to cut the kernel panics... it's clear the issue is hardware related having to do with utilization of the two GPUs, so if you effectively kill one (at least openCL) it should help stability. Everything else is a shot in the dark... not to discredit anyone's efforts but I don't see any real reason why the Eugy84 hack would work (it certainly didn't for a lot of people here), and that old gfxCardStatus utility is for MacBook Pros with a discreet and integrated GPU. I doubt it would do anything on a Mac Pro. But if certain steps seem to help out, then by all means..
That being said I am really curious if anyone else has replicated the issue on Mojave developer beta 4 or newer, as mentioned it's been stable for me and it's been my longest streak yet without any kernel panic.
