/**
 * <p>By default, all vCPUs for the instance type are active when you launch an instance. When you
 * 			configure the number of active vCPUs for the instance, it can help you save on licensing costs and
 * 			optimize performance. The base cost of the instance remains unchanged.</p>
 *          <p>The number of active vCPUs equals the number of threads per CPU core multiplied by the number
 * 			of cores. The instance must be in a <code>Stopped</code> state before you make changes.</p>
 *          <note>
 *             <p>Some instance type options do not support this capability. For more information, see
 * 				<a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/cpu-options-supported-instances-values.html">Supported CPU
 * 					options</a> in the <i>Amazon EC2 User Guide</i>.</p>
 *          </note>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { EC2Client, ModifyInstanceCpuOptionsCommand } from "@aws-sdk/client-ec2"; // ES Modules import
 * // const { EC2Client, ModifyInstanceCpuOptionsCommand } = require("@aws-sdk/client-ec2"); // CommonJS import
 * // import type { EC2ClientConfig } from "@aws-sdk/client-ec2";
 * const config = {}; // type is EC2ClientConfig
 * const client = new EC2Client(config);
 * const input = { // ModifyInstanceCpuOptionsRequest
 *   InstanceId: "STRING_VALUE", // required
 *   CoreCount: Number("int"),
 *   ThreadsPerCore: Number("int"),
 *   NestedVirtualization: "enabled" || "disabled",
 *   DryRun: true || false,
 * };
 * const command = new ModifyInstanceCpuOptionsCommand(input);
 * const response = await client.send(command);
 * // { // ModifyInstanceCpuOptionsResult
 * //   InstanceId: "STRING_VALUE",
 * //   CoreCount: Number("int"),
