Post says, he has a 2012 5,1. If he is booting of NVMe now, means he has to have bootrom 144.0.0.0.0. So OS should be Mojave at least.It's always helpful if you have a signature that explains what your system is, and what macOS you're runing.
First BootROM that have bootable NVMe support is 140.0.0.0.0 and you can boot any supported macOS version with 14x.0.0.0.0, back to 10.6.8. macOS NVMe support starts with Sierra for 4KB/sector blades and High Sierra for 512bytes/sector blades. At best, you can deduce that for bootable NVMe support the macOS release is Sierra or newer.Post says, he has a 2012 5,1. If he is booting of NVMe now, means he has to have bootrom 144.0.0.0.0.

...and in this case he does not need OpenCore nor installing Catalina (which i would still strongly recommend to avoid on a productively used system) to get things set up. Mojave’s Disk Utility should be more than sufficient. Why make things (a lot) more complicated than they need to be?
Only question is, if he prefers performance (which means Raid 0) or data security (which means Raid 1).
Sure it's 140.0.0.0.0 and not 144.0.0.0.0. Sorry for that!First BootROM that have bootable NVMe support is 140.0.0.0.0
