How to close the gpu module?
please help me, thank you.

Hi wm18822827507,

May I know why you want to disable the GPU module? Any specific requirement?
If just want to monitor the usage, you can use tegrastats, see:

I want to know if CPU performance can be improved after shutting down or reducing gpu performance. I need CPU to be faster

I don’t think disable GPU help CPU performance. You can boost the CPU performance from below command.

sudo su
nvpmodel -m 0
