Remove fields from nested struct

I have this struct of preload records.
I want to remove
__meta__ and Ecto.Association.NotLoaded from the main struct as well as from the nested array of preloaded records. To make it a simple map

  %Facility{
  __meta__: #Ecto.Schema.Metadata<:loaded, "facilities">,
  id: 4875,
  instance: #Ecto.Association.NotLoaded<association :instance is not loaded>,
  name: "Facility",
 units: [
%Unit{
  __meta__: #Ecto.Schema.Metadata<:loaded, "units">,
  facility: #Ecto.Association.NotLoaded<association :facility is not loaded>,
  facility_id: 4875,
  id: 1593,
  name: "Storage",
  rooms: #Ecto.Association.NotLoaded<association :rooms is not loaded>
},
%Unit{
  __meta__: #Ecto.Schema.Metadata<:loaded, "units">,
  cdc_location_class_id: nil,
  facility: #Ecto.Association.NotLoaded<association :facility is not loaded>,
  facility_id: 4875,
  id: 1594,
  name: "Storage unit",
  rooms: #Ecto.Association.NotLoaded<association :rooms is not loaded>
}
],
users: #Ecto.Association.NotLoaded<association :users is not loaded>
}

Is it possible?

Thanks
