Catalog Query - Optional Choices

I’m working on a new catalog template for the community catalog. Is it possible using the templating options available to allow for an ‘optional’ service deployment?

I have a container i wish to deploy as part of this stack but only if a user requires this feature, just wondering if that’s possible currently?

Thanks

Ed

I think the only way to do this today would be a variable for the scale that could be set to 0.
