    1) My question is if it is better to backup this NTFS volume to a basic disk using the“Enable optimized backup of Windows deduplicated volumes” and a scheme of weekly full and daily incrementals

    no dedupe - but you could enable compression - but ultimately required storage expands with retention.

    2) use a MSDP pool with accelerator, to reduce the impact of full backups and the need of huge basic disk? (non optimised backup)

    this is what I would do, especially if you have on disk retention of over a week.

    3) Further more, can I use windows change journal with accelerator to backup NTFS deduplicated volumes (non optimised backup)?

    yes, good idea - combine it with client-side dedupe to move even less data via the LAN

I think you should refer this for official post

Also the statement

Change journal in NTFS would work only when NetBackup client sees it as an NTFS file system. If you are NFS/CFS mounting that file system somewhere else and backing up, NetBackup Accelerator cannot take advantage of NTFS. However, track log is capable of tracking changes even without file system level change journals. In my opionion, that is the true value of NetBackup Accelerator.
