Config Setting for S3 without NFS Caching
Is there a config setting to indicate that S3 is operating without NFS Caching?

In 4.2, out of box implementation, if you choose to use S3 as secondary
storage, NFS staging is required. But theoretically speaking, for certain
hypervisor, this is not required, for example, Hyper-V. However, to make
such special configuration work, you need to extend our default data
motion service implementation. The reason why UI shows a checkbox for user
to optionally add cache storage when they add S3 secondary storage is for
such use cases, where you want to share a NFS cache for two S3 secondary
storages. In that case, you have already added cache storage when you add
the first S3, thus in adding the second S3, you don't need to add cache
again.

GUI specifically let's you turn it off. Try adding S3 secondary storage.
Source code calls it 'cache'. See https://issues.apache.org/jira/browse/CLOUDSTACK-3215

I thought we don¹t even call it cache but staging area :)

It looks like Tom tried something similar and filed CLOUDSTACK-3221.
Is object store without the NFS cache a supported configuration? I
thought the cache was a reqd.

Current code does not have that, that may be a good suggestion. You can file a ticket for that.
