+= Using in-tree modules with the device plugin
+
+In some cases, you might need to configure the KMM Module to avoid loading an out-of-tree kernel module and instead use the in-tree module, running only the device plugin. In such cases, you can omit the `moduleLoader` parameter from the `Module` custom resource (CR), and leave only the `devicePlugin` section, as shown in the following example.
