no, that's not possible as the rules for checking the PDF are only implemented for PDF/A-1b.
Any provision that differs between PDF/A-1b and PDF/A-3 wouldn't be picked up.

There hasn't been a lot of demand (or at least people didn't explicitly ask for it) for PDF/A-2
and PDF/A-3 validation using PDFBox as well as there haven't been any contributions.

Please also note that there is an open source project called veraPDF [veraPDF.org] which is
looking to implement PDF/A-1 to PDF/A-3 validation. The parsing is done using PDFBox.
