Is there a function to apply QoS parameters as a file?

I'd like to apply Qos parameters at once. Is there a function to apply QoS parameters as a file? Or is there a way to configure QoS parameter set? If so, please provide a simple example code.

For example,

// qos_policy.json file 
{
 "some entity" : {
     "some qos policy" : "value"
  }
}

There seems to be a similar concept in ROS2 I think. https://github.com/ros2/rmw/blob/humble/rmw/include/rmw/qos_profiles.h

Thank you in advance.
