How to turn off kernel_task on Big Sur?

I would like to turn off kernel_task.

Where is kernel_task?

As discussed here, it is prelinked with KEXTs. So by changing KEXTs, it can be turned off?

Could anybody show me how to turn off kernel_task on Big Sur?

It is not possible to turn off kernel_task - except by turning off your computer.

kernel_task is not a normal process (running program), but rather a representation of some of the functionality that is implemented by the operating system kernel. Amongst functionality implemented by the kernel is for example: accessing disk drives (also SSDs), communicating on networks (Ethernet, WiFi, etc.), talking to peripherals (such as making keyboards, trackpads work and getting things to show up on the display). If you could disable kernel_task, it would cause all programs that require the operating system (that is effectively all programs on your computer) to stop working.
