The new ESP32-C6 module and development board work with the ESP-IDF v5.1, currently under development (see progress report), and some basic documentation can be found on read the docs.

If you can’t purchase an ESP32-C6 module or board just yet due to limited supplies, don’t despair as more are coming very soon as Espressif tells us to expect more products on Adafruit, Akizuki, Digikey, and Mouser.
