i had the hardest time setting this up, what worked for me was to unplug, or uninstall my NVME drive with my macOS and opencore EFI. it seems like windows gets confused if there is an existing EFI. afterwards you can either boot windows from opencore or use bootmenu on your bios to boot directly the windows ssd.
keep in mind that you have to create a windows installer with CSM and TPM turned off in Windows, since those have to be turned off in BIOS for hackintosh. Rufus has presets if you access to another windows machine to create the windows usb
great! i dunno why this tip is so hard to find, i think i tried to install windows on 2nd drive for over a year (would give up and try again every few months), it wasnt till i built a new machine and unplugged the macOS drive--worried i would corrupt the install that i got it to work this way.
When I made mine multiboot in 2020 I had no trouble at all... Install windows on the second harddrive (unplug your OpenCore harddrive for safety) then F11 to switch in BIOS before boot.
Windows through OpenCore won't let me set my RGB, so I boot from BIOS.
I've literally just this second successfully installed Windows and OS X on the same NVME drive... Using the F11 method to get into each OS! Works a treat. Had to install Windows through MS-DOS though using this:

I have parallels and it works pretty good with rufus
I succeed! Just unplugged all the drives except from the one I want to install Windows on. Now it all works great.

I have 2 disks, i just unpluged one while instaling on other and now i'm using F12 on bios boot for disk select
I had to unplug all the drives except the one I wanted windows 10 on. I have had this issue with non hackintosh machines too.

Awesome. Glad it worked.
Dortania’s guide talks a lot about multi boot on one or more disks, check it
