How to control Realm synchronization at field level?

now, i have a realm model like this:

class Task: Object, Identifiable {
    @Persisted(primaryKey: true) var _id: ObjectId
    @Persisted var title: String = ""
    @Persisted var isCompleted: Bool = false
    @Persisted var priority = Priority.medium
    @Persisted var notes: List<Note> = List<Note>()

The data corresponding to these attributes will be stored locally on the client, and if I enable Device sync, these data will also be synchronized to the cloud. My question is, how to control the synchronization of some fields, for example, I want the data in the “priority” field to be saved only locally, not to be synchronized to the cloud, how should I do it? Thank you~ :grinning:
