I came searching for something slightly different. just in case someone needs same as me.

you can specify specific fields to auto-populate during creation of schema as shown below

const randomSchema = mongoose.Schema({
  name: {type: String,trim: true},
  username: {type: String,trim: true},
  enemies: { 
    type: ObjectId, 
    ref: randomMongooseModel, 
    autopopulate:{
      select: '-password -randonSensitiveField' // remove listed fields from selection
    }
  },
  friends: { 
    type: ObjectId, 
    ref: randomMongooseModel, 
    autopopulate:{
      select: '_id name email username' // select only listed fields
    }
  }

});

I am using mongoose-autopopulate plugin for this example
