Click OK.
In the Categories pane, select Machine Types and drag-and-drop the vSphere Machine component onto the design canvas.
On the General tab for the machine, complete the necessary information, including the maximum number of instances of the NSX machines.
On the Build Information tab, select to clone the machines and specify the necessary information.

Select the created blueprint and click Publish.
The new blueprint is published in vRealize Automation.
Once the blueprint is published, create an NSX provisioning service in vRA Catalog. See Creating a VM Request Service in vRealize Catalog. After that, you can provision NSX machines and scale out the NSX deployment.
