is there a way to override a dataset object saved with save_to_disk?
I'm not sure I understand your issue, can you elaborate ?

`cache_file_name` is indeed an argument you can set to specify the cache file that will be used for the processed dataset. By default the file is named with something like `cache-<fingerprint>.arrow` where the fingerprint is a hash.
At the moment when I use save_to_disk, it uses the arbitrary name for the arrow file.  Is there a way to override such an object?
