disable zoom, dragging in gvisMap - r

Question

Is there a way to entirely disable dragging and/or zooming in gvisMap, and remove the zoom control also? I have looked at options under google.com developers docs referenced in the help for gvisMap(options) but can't see this control.
Broadening the scope of the question to include alternative packages, I note that plotGoogleMaps() in R package plotGoogleMaps has an option draggable=FALSE, but there is no corresponding parameter to disable zoom, and rendering it in shiny is not so simple as renderGvis(). I had a quick look at RgoogleMaps package also.
Background: I particularly want a google satellite map for the transition to street view, I set the map bounds from a zoom/drag enabled leaflet map, so enabling zoom/drag on the google satellite view is redundant/confusing. Disabling these capabilities is a detail that would improve the UX.
[edit] This revised example is a bit longer but shows in full the functionality I am referring to. It works fine apart from some niggles such as I don't know why the fudge factors are needed, and I don't know how to turn off the markers in the google map - but these are outside the scope of my question. The specific subject of my question however is: can I disable drag and zoom on the google map, just like I do in leafletOptions(zoomControl = FALSE, dragging = F)? If I had a supplementary question, it would be something like 'how do I reduce the proliferation of google mapping packages?' - but that is not a valid question for this forum. That said, I'd welcome any broader steer on how to simplify this.
