Graph diver installation


I recently acquired a new computer, and I need to install a graphic driver. The model name of the graphic card that I heard was RTX A5500. To double-check the graphic card of the computer, I ran the command $ lspci | grep VGA and the result was as follows: 0000:3:00.0 VGA compatible controller: NVIDIA Corporation Device 2233 (rev a1). I would like to ask if this is indeed an RTX A5500.

Additionally, could you provide me with a link for the appropriate graphic card driver for this model? My operating system is Ubuntu 20.04. Furthermore, I have to install this in an environment without internet access, so I would appreciate it if you could guide me on how to proceed with this as well.

Thank you.
