I'd like to submit a kernel patch for a new sysctl to use EFI instead of ACPI for poweroff + reboot

Sorry, I meant to say, "Are you using a Threadripper 2 as well?", of course it's a TR4 socket board ... sigh.

It allows me to power off my ASRock X399M (mATX) motherboard, and should also work for ASRock X399 (ATX) users who have reported the same problem of ACPI hanging during shutdown. Hopefully it will be useful to other users in the future who experience ACPI shutdown issues as a fallback option.
