Rest API update fields not working as expected

Hey there,
I'm having an issue when trying to update ACF fields using Rest API.
Following the documentation https://www.advancedcustomfields.com/resources/wp-rest-api-integration/ .
We should be able to update each field/property separately, but when i try to make a POST request.
It throws me an error, says that a property is required. It's like the request is trying to replace the whole ACF structure
instead of just trying to update one field

I'm using POSTMAN to test this out

Request:

curl --location --request POST 'https://example-site.com/wp-json/wp/v2/product/3295?acf_format=standard' \
--header 'Content-type: application/json' \
--header 'Authorization: Basic HIDDEN' \
--header 'Cookie: PHPSESSID=HIDDEN' \
--data-raw '{
     "acf": {
        "section3_video_bunny": "123"
        }
}'

Response:

{
    "code": "rest_invalid_param",
    "message": "Invalid parameter(s): acf",
    "data": {
        "status": 400,
        "params": {
            "acf": "star_rating_average is a required property of acf."
        },
        "details": {
            "acf": {
                "code": "rest_property_required",
                "message": "star_rating_average is a required property of acf.",
                "data": null
            }
        }
    }
}

Start with the ACF WordPress REST API integration documentation and reproduce the POST request shown against the /wp-json/wp/v2/product/3295 endpoint. Trace how the acf parameter validates required properties; done means updating section3_video_bunny without requiring unrelated ACF properties, with the request and response behavior covered by an appropriate test.
