+==== Configuring kernel arguments for the Discovery ISO by using GitOps ZTP
+
+{product-title} now supports specifying kernel arguments for the Discovery ISO in GitOps ZTP deployments. In both manual and automated GitOps ZTP deployments, the Discovery ISO is part of the {product-title} installation process on managed bare-metal hosts. You can now edit the `InfraEnv` resource to specify kernel arguments for the Discovery ISO. This is useful for cluster installations with specific environmental requirements. For example, you can define the **rd.net.timeout.carrier** kernel argument to help configure the cluster for static networking.
+
+For more information about how to specify kernel arguments see the following documentation:
