Can't find my NVME drive on boot options

[Picklerick]

Hi! So my new pc is actually fine and working very well but I'm running into a bit of a problem that really bothers me.

 

I have my windows 10 on my NVME drive and it's working well but when I go to the bios, boot option #1 (and this is the only one that can be picked) is my old HDD labelled Windows boot manager for some reason. The only way my two other ssd's show up in the boot option is if I enable CSM ( I watched a yt vid saying it should be disabled) other than that nothing. It just worries me that this might be a problem in the long run. 

 

Any help would be appreciated, thank you!

Boot drive: WD Blue 500Gb NVME Ssd (GPT volume if ever that's needed)
