Hi, can I adjust (decrease) the wifi signal strength on esp-idf?

By running "make menuconfig" within the ESP-IDF project directory, you will see a list of properties that affect that project. Within the "Component config" -> "ESP32-specific config" sub menu you will find an entry called "Max TX Power (dBm)" that is set to a value of 20 (maximum). You can reduce the transmission power there.
