Both my disks are GPT.
  1. PNY XLR8 CS3030 256GB Nvme M.2 SSD (OS)
  2. TeamGroup GX2 1TB SATA SSD (Games and stuff)
When i disable the CSM and switch to UEFI, only the boot drive (M.2) is showing up and the SATA SSD is not showing up.

According to this post, MBR will not be shown from the BIOS when moving to UEFI. But for me, its disappearing on the UEFI mode while being GPT.

Any solution to this? I want to disable CSM since my PC boots with an ugly low res image.

Windows is running in UEFI not legacy.

In list of devices in boot order only bootable drives show up.
Since TeamGroup GX2 1TB SATA SSD is not bootable, it will not show up in boot order.
This behavior is specific to UEFI mode (because you disabled CSM).
So you are suggesting that even if it is not showing up, i will be fine and still can use it?
