Remove vertex.tooltips from ndtv d3movie

I'm plotting a dynamic network visulisation using the Statnet, networkd3, and ndtv packages.

In the vignette for this package, the authors explain how to "generate interactive html tooltips to be displayed when the vertices are clicked on":

render.d3movie(
  toy_epi_sim,
  render.par = render.par,
  plot.par = plot.par,
  vertex.cex = 0.9,
  vertex.col = "ndtvcol",
  edge.col = "darkgrey",
  vertex.border = "lightgrey",
  displaylabels = FALSE,
  vertex.tooltip = function(slice){paste('name:',slice%v%'vertex.names','<br>',
                                         'status:', slice%v%'testatus')},
  output.mode='htmlWidget')

However, I'd like to remove these tooltips, since by default they just show meaningless node IDs, and I'm already showing node labels instead.

Things like vertex.tooltip = F or vertex.tooltip = NA don't work - how do I turn off vertex tooltips?

This is the code I'm using:

render.d3movie(net, usearrows = T, label = "gmv_label",
               displaylabels = T,
               bg="#ffffff",
               edge.col = "#ff0063",
               vertex.col = "colo",
               vertex.cex = "amount",
               edge.lwd = 5,
               launchBrowser=T, filename= XXX,
               render.par=list(tween.frames = 30, show.time = F),
               plot.par=list(mar=c(0,0,0,0)))
