SBI bank acc address has no relation with sbi cc application as sbi cc application rely solely on aadhaar address as authenticated via digilocker.
Yes. Likely but no guarantee.
They do any bank acc verification via netbanking not just sbi netbanking & vkyc is skipped if person verified their bank acc via sbi netbanking or they verify via netbanking of another bank acc which has ckyc linked to it (not all banks have ckyc linked to their bank acc customers assuming customer has ckyc). ID & address details are only fetched via aadhaar digilocker authentication.
