Want to upgrade Mac Pro 5,1

I've just done a fresh install of High Sierra on my Mac Pro 5,1.

The machine has 48gb ram and a sapphire RX 580.

I also have 500gb ssd NVMe that I would like to put a new OS onto (doesn't currently have any OS on it as I wiped that too after breaking it during an attempt to update).

Can anyone tell me a general how to put a new OS on the SSD? I have used open core before to patch my MBP but that was to the drive that I was currently running my OS off. Wondering where I need to put OCLP if I am putting the OS on the SSD.
