Restoring an arw image?

Question

Data recovery

There is a memory card, you need to recover deleted files of the arw (Sony) format from it. The problem is that all the enumerated programs, about 7-10, unanimously repeat that it is not possible to recover the overwritten files. The maximum that could be done was to pull out these files in this form https://yadi.sk/d/cZd4JWqWEu6xOQ The

question is on the verge of life and death. It was graduation. The pictures were deleted after a couple of days, they came to their senses after a couple of days of using the memory card. Is it possible to restore them? There is a hex code for these images if that helps.
