/**
 * <p>Modifies the specified attribute of the specified instance. You can specify only one
 *             attribute at a time.</p>
 *          <p>
 *             <b>Note: </b>Using this action to change the security groups
 *             associated with an elastic network interface (ENI) attached to an instance can
 *             result in an error if the instance has more than one ENI. To change the security groups
 *             associated with an ENI attached to an instance that has multiple ENIs, we recommend that
 *             you use the <a>ModifyNetworkInterfaceAttribute</a> action.</p>
 *          <p>To modify some attributes, the instance must be stopped. For more information, see
 *                 <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Using_ChangingAttributesWhileInstanceStopped.html">Modify a stopped instance</a> in the
 *             <i>Amazon EC2 User Guide</i>.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { EC2Client, ModifyInstanceAttributeCommand } from "@aws-sdk/client-ec2"; // ES Modules import
 * // const { EC2Client, ModifyInstanceAttributeCommand } = require("@aws-sdk/client-ec2"); // CommonJS import
 * // import type { EC2ClientConfig } from "@aws-sdk/client-ec2";

 *
 * @throws {@link EC2ServiceException}

 *
 * @example To enable enhanced networking
 * ```javascript
