@tkimnguyen not really
We had dash docssets for Plone 4, and something like a year ago or so we removed dash support.
According to our download stats, and user feedback almost no one was downloading and using them.
Dash support is still in the old as Plone 4 papyrus setup, but well, like I said comparing time and work effort to the user base (it was besides me one other user) does not cut it.
Because of that the docs team decided to do not create docsets anymore.
One other reason is that dash is macOS, the alternatives like zeal (linux) are working sometimes different, depending on your docs setup and sometimes these alternatives are also not in active development since some time.
