Device_pm zephyr sample does not work - can not assign CONFIG_PM=y

[Avgerinos89]

Hello

I was working on a project, trying to enable the power management but I could not. So I just tested the simple zephyr sample application device_pm just to see if there is any problem with my code.

But unfortunately when I open the sample application device_pm (https://github.com/zephyrproject-rtos/zephyr/tree/main/samples/subsys/pm/device_pm)
using the nrfConnect SDK v2.9.0 it does not allow the CONFIG_PM to get the value y
As you can see in the following screenshots:

In the build configuration I use the board nrf52840dk/nrf52840 which is compatible with the sample. 

I am using a MacBook Air M3, 15.2
Also I build using the nRFConnect SDK 2.9.0 and the Visual Studio Code with the nRFConnect extension.

Is there anything wrong with the latest SDK 2.9.0, or using a MacBook (ARM) to develop? 

Thank you

I encountered the same problem some time ago, https://devzone.nordicsemi.com/f/nordic-q-a/105197/nrfconnect-2-5-0-config_pm-cannot-be-set-to-y-in-kconfig-with-nrf52833
