I don't think so, but I don't think you really want that. options(rgl.useNULL = TRUE) doesn't stop rgl from running, it just stops it from trying to display anything. So you could put code like if (!interactive()) options(rgl.useNULL = TRUE) into your .onLoad function for your package, and it wouldn't try to open a display on CRAN, or anywhere else that wasn't interactive.
