Spring boot MongoRepository saveAll() only if doesn't exist

Question

I'm trying to use save multiple documents in Spring boot data mongoDB with saveAll() but not sure if there is a way to verify if the documents exist before inserting to prevent duplicate entries. If I use save() instead, I should be able to avoid duplicate entries by checking if documents exist prior to each insertion. But instead of call save() multiple times I want to use saveAll() but I'm unable to check if any of the documents exist before inserting. Does any one think this would be possible?

for the initial insert I can use saveAll() an insert the below document all at once

[
    {
        "model": "Highlander",
        "make": "Toyota",
        "year": "2022",
        "color": "Black",
        "condition": "Used"
    },
    {
        "model": "Explorer",
        "make": "Ford",
        "year": "2020",
        "color": "Silver",
        "condition": "Used"
    },
    {
        "model": "Acadia",
        "make": "GMC",
        "year": "2023",
        "color": "Black",
        "condition": "New"
    }
]

and if I try to re-insert this same document with saveAll(), it would go through without a problem but it would be a duplicate document and I want to prevent that and what I'm trying to figure out is would it be possible to check if the document exist before saveAll() takes place to prevent duplicate entry.
