The **setconfig** RPC command allows you set the (dynamic) configuration option named by `config`: options which take a value (as separate from simple flag options) also need a `val` parameter.
You can see what options are dynamically adjustable using lightning-listconfigs(7). Note that you can also adjust existing options for stopped plugins; they will have an effect when the plugin is restarted.
