Yes, you can change the file metadata's ACL just like any other Kinvey entity; if you are using the REST API, you can simply use a PUT request. If you are having difficulty finding a way to do this using a specific library, please post in that library's category to get a more specific answer.

Thanks for you answer, I am using the kinvey-angular.js library and I don't know how can update the ACL.

The file metadata can be updated by using [`Kinvey.File.upload()`](http://devcenter.kinvey.com/angular/guides/files#Uploading). Unfortunately, you'd have to pass in the actual file as well, the library doesn't handle updating information without this.
As a workaround, you could implement the `PUT /blob/:appKey/:id` request itself, as suggested by Gal. Information on that can be found [here](http://devcenter.kinvey.com/rest/guides/files#Uploading).

If it is possible, how can I make it?
