I suggest we put the (Socket offloading configuration) in a separate config file like it is done here: https://github.com/zephyrproject-rtos/zephyr/blob/main/samples/net/sockets/echo_server/overlay-nsos.conf

omg the code snippet in the comment went wrong. this is not about the PTY but about the socket offloading

Lets try to keep the specific native sockets implementation in a separate config file, like it is done in echo_server example, in case we want to be able to run with tap (which is the default behavior currently in Zephyr)
