CAM_FEEDBACK_PIN and BRD_PWM_COUNT Interaction

I have CAM_FEEDBACK_PIN set to 53, Aux 4 for fast capture method. I am not sure if my application needs this, but it sounded like there were not any drawbacks.

When BRD_PWM_COUNT is set to 4 or higher cam feedback fails, I have also tried 7 which in MP says “3 PWMs and 1 Capture”

Is there a way to enable AUX 5 and 6 PWM while keeping AUX 4 fast capture cam feedback?
