Hello Tim,
Yes, this is possible. In case of a
Custom Drop Zone scenario, the whole Upload widget may be hidden by applying CSS style "display: none;" to it -

And in case of an
Asynchronous Upload, "Select files..." button may be hidden by applying "display: none;" to it as well. And in order to preserve the height of the dropzone after that, a style for setting its height should be applied -
sample Dojo based on the demo.
