I don't think GMS has support built in for DragonBones, but you could always create one manually. I had never heard of DragonBones (I use Spriter Pro), it looks interesting.
I started using it last year and once I got the hang of it, I started to really enjoy using it. Sadly there is no GMS support but I export my animations as inage frames and that works fine.
I'll post some gifs of stuff I made for my jam games.
These first 3 were the first animations I made with Dragonbones.
