[Feature Request] Hide CPU Section in Terminal

[XiaomoWu]

Required prerequisites

• I have searched the Issue Tracker that this hasn't already been reported. (comment there if it has.)
• I have tried the latest version of nvitop in a new isolated virtual environment.

Motivation

This issue is related to #160 but from a different perspective, so I think it's better to create a new issue.

Currently, the CLI interface always includes a dedicated CPU section. There's no way to disable it (see screenshot below):

In my use case, I already opened an hop pane to track CPU usage. The information from nvitop become redundant. More importantly, when system RAM usage is high, nvitop stops displaying the actual memory usage and instead falls back to showing only a percentage (e.g., “USED: 18GiB” -> "83%"). This makes it harder to interpret memory load accurately, and I have to rely on htop to get the real numbers.

Solution

I propose adding a new argument to disable the CPU section in the terminal:

nvitop --no-cpu

This would streamline the interface for users who already monitor CPU usage elsewhere and help preserve useful RAM information in high-usage scenarios.

Thanks again for the fantastic tool!
