DGXOS reviews drivers before updating

I am currently using DGXOS 5.5 in a closed network environment and I would like to upgrade the gpu driver to 535.104.05 as a customer’s request, but I have a question.

  1. In the dgxos user manual, it is called driver installation with apt, can it be installed through an official driver?

  2. If it doesn’t work, I want to mirror the apt server, but do I just mirror the Ubuntu apt repository and the nvidia container cookie repository?
