DLC in The Technomancer is listed here.
According to an interview with Spiders, the game will not feature DLC. Spiders CEO Jehanne Rousseau had this to say about DLC: "Honestly, I’m not too fond of DLCs for RPGs. For strategy games maybe it makes sense to have DLC to bring in for example new tactical units or scenarios for example. However for RPG games I believe if you are making DLC, you are delivering only parts of your game and I don’t like that."
