If you want to disable Plug & Charge for a short-time period (e.g. troubleshooting at a station), you can quickly turn it off by using the Plug & Charge toggle in the vehicle's charging settings.
If you would like to disable Plug & Charge for a longer time period or stop using Plug & Charge altogether (e.g. because you have sold your vehicle), you should uninstall the certificate from the vehicle and remove the Plug & Charge option from your charging tariff.
