The FC can't itself act as a motor driver but it can output pwm signals to a separate motor driver. If driving DC motors an h bridge or h bridge breakout can help to control the direction and current or torque roughly speaking sent to a motor a L298N I think is the part number has two h bridges and is a single pretty cheap chip:

Basically you feed power for motors into here (can use buck converter to step down main battery voltage) and then send pwm signal into it from FC to drive the motors with the separate power (coming from buck converter or other power probably with common GND)
TB6612FNG H-Bridge with Arduino - Better Than L298N?
I’ll show you how to use the TB6612FNG dual H-Bridge motor controller. It’s a MOSFET-based device with many advantages over the popular L298N.
