Dragon Tamed Message and Disappering

Hello, I am a beginner and thought I start learning modding on the dev kit, by making the dragon boss a tameable mount.

I have copied all the dragon files across to my mod folder and edited the renamed dragon blueprint file.
I can not see where I would stop the message you get when its tamed and the section where you would stop it despawning, I am hoping someone can help.
Also does the dinos normally attack when you click play in the dev kit? as its not doing.

Thanks all.

look in the graph of the dragon bp and disable it there
