Is it possible to ask for items to be added to the agenda?

Yes. Shareholders who, severally or jointly, represent at least 2,5% of the Company share capital may ask for items to be added to the agenda, within 10 days from the publication of the notice calling the Shareholders' Meeting, unless a different term is provided by the law, indicating the further proposed items in their request.
Requests must be submitted in writing.
Additions to the agenda cannot be made for the matters upon which, according to law, the Shareholders' Meeting will resolve on the basis of a proposal of the Directors or on the basis of a project (example: financial statements) or report of the Directors different from the report on the items on the agenda.
The Board of Directors gives notice of the allowed additions to the agenda at least 15 days before the date set for the Shareholders' Meeting, unless a different term is provided by the law, in the same ways prescribed for the publication of the notice calling the Meeting (publication on Eni's website, transmission to Borsa Italiana and publication on at least a newspaper  with national circulation).
Within the deadline for submission of a request to add items to the agenda, the requesting shareholders shall provide to the Board of Directors a report on the matters they propose should be debated.
The Board of Directors makes the report available to the public, together with its own evaluations, if any, at the same time as the publication of the notice of additions to the agenda at the Company's registered office, on Borsa Italiana and on Eni's website.
