KACE Product Support

I was recently told that we can push BIOS updates using Managed Installations using DUP files released by Dell so that we can input the passwords as installation switches (for BIOS that have admin passwords configured), but I can't find any of these DUP files to download. 

Are they still releasing these? 

I need to have a way of pushing BIOS updates to my computers and if KACE doesn't support it, then we will either need to do it manually or find a new product that can do it.
