The B58 has water injection to prevent thatYes, BMW has been utilizing direct injection on their 3.0L turbo engines since the N54 (back in 2006).
The big question is if the Supra engine will be utilizing its D4S dual injection system (port and direction injection) as this fuel system has been key with preventing carbon build up on the Lexus engines that incorporate this technology (as well as the FA20 used for the 86 twins).
Edit: I mispoke, it has a revised PCV system with upcoming models to have water injection
