Deploy GPU Operators in a disconnected or airgapped environment

Hello all,
Please we are looking to implement the above url Deploy GPU Operators in a disconnected or airgapped environment in our organization but the doc is abit confusing or maybe not having enough/workaround to follow to implement.
currently we are facing issues with installing the operators in our cluster as our current platform is OC 4.7.33.
Please is there any better alternative i could follow to configure and Deploy Nvidia GPU Operators in a disconnected or airgapped restricted network environment?.

We do not have third cluster/server which have open internet access so what would be an alternative to achieved this?.
Please any help to successfully implement this would be appreciated
Thanks
