 - `spec.state`: Determines whether to install (`present`) or uninstall (`absent`) the plugin.
 - `spec.values`: Allows users to provide custom values for manipulating Helm chart values. This field is immutable, 
   requiring users to recreate the object to pass new values.
+- `spec.values.nri.plugin.index`: A plugin index to register to NRI. The plugin index is used by NRI to determine in
+  which order the plugin is hooked into pod and container lifecycle event processing with respect to any other.
+- `spec.values.nri.runtime.patchConfig`: Enable/Disable NRI on the current runtime.
+- `spec.values.nri.runtime.config.pluginRegistrationTimeout`: Timeout for a plugin to register itself with NRI. Ensure
+  that both timeouts are either left unspecified or specified together, and `patchConfig` must be set to true to update
+  the timeouts. Timeouts will have no effect if `patchConfig` is set to false.
+- `spec.values.nri.runtime.config.pluginRequestTimeout`: Timeout for a plugin to handle an event/request. Timeout for
+  a plugin to register itself with NRI. Ensure that both timeouts are either left unspecified or specified together, and `patchConfig` must be set to true to update
+  the timeouts. Timeouts will have no effect if `patchConfig` is set to false.
 - `spec.status`: Tracks the basic state of the resource and includes basic messages in case the operator encounters 
   issues while reconciling the object.
