Your system is only recognizing a single NVIDIA GPU. lspci reports that, dmesg supports that, and nvidia-smi reports that.

Everything is consistent. Either you have only one NVIDIA GPU, or the 2nd GPU is configured in such a way that it is completely invisible to the system.

Plugged in the wrong slot, no power, etc.

Even your SBIOS does not see the 2nd NVIDIA GPU, as indicated by lspci.

You’ll need to sort things out by rearranging cards or trial an error. I can’t tell you precisely what is wrong.
