2 layer PCB

Well, I may need to design a board with ESP32 bare chip (not module) on a 2 layer board.
Passing FCC is mandatory.
Any pioneer can tell me if it is possible, any rules-of-thumb, or I'd better starting with 4 layers?
The project is just at planning stage. It is better to make sure than sorry later.
Thanks
BS
