It’s possible to control the interactions of the network with visInteraction() :

Frozen network

dragNodes : enable or not the selection and movement of nodes (click on a node, and move your mouse)?
dragView : enable or not the movement of the full network (click everywhere except node, and move your mouse) ?
zoomView : enable or not the zoom (use mouse scroll) ?

visNetwork(nodes, edges, height = "500px", width = "100%") %>% 
  visInteraction(dragNodes = FALSE, 
                 dragView = FALSE, 
                 zoomView = FALSE) %>%
  visLayout(randomSeed = 123)

Hide edges/nodes on drag

Can increase the performance.

hideEdgesOnDrag : hide egdes when dragging the view
hideNodesOnDrag : hide nodes when dragging the view

visNetwork(nodes, edges, height = "500px", width = "100%") %>% 
  visInteraction(hideEdgesOnDrag = TRUE) %>%
  visLayout(randomSeed = 123)

Navigation buttons

We can show navigation buttons with navigationButtons :

visNetwork(nodes, edges, height = "500px", width = "100%") %>% 
  visInteraction(navigationButtons = TRUE)

And also…

keyboard : enable keyboard manipulation rather than mouse (click on network before)
hover and hoverConnectedEdges : control hover
selectable : disable nodes and edges selection
tooltipDelay : set delay before show pop-up
…

visNetwork(nodes, edges, height = "500px", width = "100%") %>% 
  visInteraction(keyboard = TRUE, tooltipDelay = 0)
