Powering Servo Rail of PM07 Using SBEC

I’m currently working on a capstone project focused on designing and developing a UAV with Vertical Takeoff and Landing capabilities. Our team plans to create our own aerostructures and airframe. Presently, we’ve configured it as a tri-copter with a rear motor for yaw control and two front motors connected in parallel. We aim to implement a tilt-wing design where all front motors tilt, while the rear motor exclusively controls yaw.

My question pertains to how power the servo rail on the PM07 for the control surface servos. Currently, we have a Turnigy Plush-32 30A 5.5V/4A SBEC for a motor that we are not using anymore. Could we use this for powering the servo rail and how would we connect this?

Thank you for any help
