Yes, it depends on the nRF Connect SDK version you are using. The solution I posted is for the latest SDK version.

On the documentation page, you can change the SDK version to see the relevant information for you.
For example, here is the documentation for v1.9.1 which suggests CONFIG_AT_HOST_UART_2:

Hi,

The suggested fix do not seem to work when placed in the .dts file.. But when

CONFIG_AT_HOST_UART_2=y is added to the prj.conf file it works?

Hi,

The at_host defaults to uart0 if you do not set another UART in the devicetree.

I assume you want this to always be on uart2 for this board?
In that case you can set this in the "chosen" node in your board files:

/ {
    chosen {
        ncs,at-host-uart = &uart2;
    };
};

If this is application specific, it can be added through an overlay file.
