I'm sorry but I don't think so (I hope I'm wrong!)
I quote Major Nelson's post here:
"Fortnite’s support for keyboard and mouse launches alongside previously announced Warframe via today’s update, with Bomber Crew, Deep Rock Galactic, Strange Brigade, Vermintide 2, War Thunder and X-Morph Defense adding support in November, and Children of Morta, DayZ, Minion Master, Moonlighter, Vigor, Warface, and Wargroove adding support in the future."
Fortnite and Warframe are ready, then a bunch of titles will be updated in November and the last couple of games will be ready in the future (dayz is in the last group: future support)
Hope it helps!
