Some news after my bug report #1239139:
kernel-firmware-nvidia-gspx-G06-cuda required kernel-firmware-nvidia-gspx-G06 located in CUDA repository.
Index of /compute/cuda/repos/sles15/x86_64
But things changed with driver >= 570. Now firmware is located in nvidia-common-G06 which is getting installed once nvidia-compute-utils-G06 gets installed.

Sat Mar 8 22:58:14 UTC 2025 - Stefan Dirsch - removed obsolete kernel-firmware-nvidia-gspx-G06-cuda; firmware has moved to nvidia-common-G06 and kernel-firmware-nvidia-gspx-G06 is no longer available either (boo#1239139)
