Stop Nero from opening tray?

I have an Antec case with a door over my optical drives. Now I turned off the eject disc after burn in the nero configuration. But if there is an error it still ejects the disc. And once I close nero after burning a dvd it opens the tray. Is there anyway to stop it from doing this?

I have been leaving the case door open but I don’t like doing this because it lets dust in the case, and one of my dogs or cat could possibly rub up against it and break it. And if the DVD had an error while I was in another room they could possibly break off the drives tray.
