You can load EZD2 into the drum track, when you render the song to wav it will render the midi track through EZD2 to wav.
You will have to edit the drum track in RealBand's piano roll.
RealBand didn't get vst sync until 2017AD so EZD2's track will just loop the first bar in earlier versions.
You can't drag midi drum phrases out of EZD2 into RealBand2015 as it will just erase the current track.
So you can just use 2015 and render to wav, update to 2018 and get both vst sync and drag in midi phrases, or just use Reaper and it will all work.
