Yes and no.
You can have P and I settings but no D as the fluctuations in the sensor reading make it less than useful.
You can alter the service interval of the Integral function wrt RPM and Load, and you can change the gain of wrt to RPM and Load too.
Overall it's very good, certainly a lot better at holding the desired Lambda than things that come in gold boxes.

Like all PID settings, they are only applicable to the application at hand. There are a few different setups depending firmware version too.
They need to be tuned for your setup.
