Ok. But you only need to drive two PWM signals to the motor drivers, to ENA and ENB. The direction pins IN1 IN2 IN3 and IN4 just need a simple digital signal.
So for seven motors you need 14 PWM signals, which you can do with one PCA9685.
Of course you also need 7*4=28 GPIO pins for the direction pins. You might have enough on the Pi, or you could use an I2C GPIO expander.
