That's one way of putting it, another is 'exposing the fraudulent interpretation of Stefanoni with the exculpatory evidence she omitted.'
Numbers' dilligence suggests the ECHR has already ruled on this issue and Stefanoni's goose is already cooked. From what I have read on her dispute with Pascali, what she is trying to do is re-brand 'fraud' and 'constructive incompetence' as something akin to 'teaching the rest of the world how to do DNA forensics.'
I wouldn't call that a dispute with Pascali. What happened is, a prosecutor in the town of Potenza appointed Pascali as DNA expert with the task testing the clothes of Elisa Claps' for DNA.
The preliminary judge thought Pascali's report was unconvincing, and decided to appoint another expert in order to make an assessment on Pascali's work. The other expert was Patrizia Stefanoni.
Patrizia Stefanoni did not have the task of testing items, but just to review Pascali's work. Stefanoni said Pascali's tests were unsatisfactory, and he did not investigate the objects properly.
So the judge ordered that the Carabinieri RIS from Rome should perform tests on the items. The result was that the Carabinieri found multiple instances of DNA of a suspect, Danilo Restivo (a serial killer who was indicted in another state for another murder).
I don't think this was a dispute between Stefanoni and Pascali. We are talking about an expert (Pascali) who egregiously failed to acomplish his duty. Had his work not been reviewed, Elisa's family would be still awaiting justice.

As for the reasons why Pascali wanted the EDFs, it doesn't really matter what the defence purpose was, what matters is that - as for the procedure code - they only have to explain the judge why they want that evidence, and why the couldn't request it before. Now you parse a judgemental phrase: "fraudulent interpretation .. exculpatory evidence..", which is rhetoric, but it is nothing but judgmental, there is no factual information in it.
What was the defence seeking? Was the defence seeking whether there was evidence of laboratory contamination in the negative controls of the contested samples, or even in those of other samples? If that's what they were looking for, they should have explained this to the judge. And they didn't.
Pascali only said he needed to know the peaks areas, this is what he explained the judge on Oct. 4. Stefanoni also deposited the negative controls she had with her. Here I'm not stating that the judge would have said "yes" to any request on the part of Pascali, but the fact is Pascali and the defence
did not make the request, and they
did not explain the intent of their requests in terms compatible with how you explain them, the defence did not say anythig on the lines of seeking "contamination that was not revealed" and see possible "fraudulent behaviours". They did not describe such alleged purpose to expose omitted evidence to the judge in the terms that you describe. They describe their purposes in such terms that a further investigation in electronig data wouldn't seem necessary to the judge: they did not explain such alleged purpose to the judge.
I do not want to draw any conclusion as for what purposes Bongiorno and Pascali had in their minds. As for Stefanoni and prosecution I can well see many good reasons for not wishing to release raw data, without any neeed to think at any conspiracy or fraud. So I don' do mind-reading. I only limit myself to recording trial facts. Those are the facts.
Stefanoni did say she was ready to present log files, but she had reservations about the way they could be manipulated, the "offer" was known to the parties insofar it belonged to the court documentation available to them, and on the hearing the defence did not make some requests, and they did not express the motivations that you attribute to them.
