By making sure the nvme drive is the only one plugged in when you install windows will determine what disc zero is
You select the drive you want to boot Windows from in the BIOS.
Alright that makes sense, Reason I'm asking is because I got confused when I recently had two HDD's only installed and had not made any disconnected,
I removed my SSD witch was disk 0 at the time and the other two drives "remained" disk 1 and disk 2 as seen in windows setup or disk management.
Then when I installed windows on disk 1 it automatically became disk 0 and disk 2 became disk 1.
Now I'm planning on installing an M.2 and an additional SSD along with two HDD's and the result I want to achieve would be like thus: M.2= Disk 0, SSD =Disk 1, HDD's =Disk 2 & 3.
Each obviously with their own partitions. And I was hoping to do this without disconnecting any drives in order to keep track of all partitions and their respective roles when in the windows setup.
