Mongo/Mongoose JS — Update document to latest state?

Question

Is there a way to store a document then get an updated value of it at a later date without needing to query and populate again?

const someDocument = await SomeModel.findOne({...}).populate(...);

// store a reference to it for use
const props = {
   document: someDocument,
   ...
}

// at a later time
await props.document.getLatest() <-- update and populate in place?
