How to disable WiFi driver to allow access ADC2?

[Simpler1]

I have an ESP32-CAM (ESP32-S) and I'm trying to use the Analog Digital Converter (ADC) to report the battery voltage, but there are no ADC pins available by default.

The documentation states:

ADC2 is used by the Wi-Fi driver. Therefore the application can only use ADC2 when the Wi-Fi driver has not started.

I'm not interested in using Wi-Fi, so how can I avoid starting (or stop) the Wi-Fi driver to get access to the ADC2 pins?

I would also be fine with disabling the camera temporarily to get access to an ADC1 pin and then reenabling the camera.

Thanks

In ESP-IDF? If you don't do anything WiFi-related, WiFi won't start.
