You could extend the camera and PhysicsFieldComponent component with a custom class and override the tick, no need to touch the source of the engine.

in physics component it’s virtual and public so you have access to it

ENGINE_API virtual void TickComponent(float DeltaTime, enum ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction) override;

same goes for the camera

ENGINE_API virtual void TickComponent(float DeltaTime, ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction) override;
