I am not sure if there is one. RDK is a pretty sophisticated addon. Your best bet is to figure out what you need to get from the addon and go through each option and ensure you have the right ones. Talk to your raid lead and ensure that you select the options they require.

Let me know if you need anymore help or need help with something specific. I am pretty familiar with that addon.

You could always make one yourself or stream the setup through discord. I think most guilds have their own setups and don't like to share for obvious reasons. That's probably why no such video exists.
