Use an AUX track for the BFD plugin. As Cliffy states, the inserts are 'post recorder', so they don't get recorded on an audio track anyway. Don't waste an audio track. The Bounce TO Disk command will bounce all the sources which are routed to the selected output (usually 1 - 2), so you don't need to go to the other steps just to 'render' it to an audio track first. Bounce To Disk will include output from your AUX channels, whether it's output from a plugin or signal from an external source, such as a HW MIDI modules, or FX box. If, for some reason, such as reducing CPU load, you do wish to render the BFD output to an audio track, you can use the steps Cliffy described.
