if you have applied online you have been flagged in the system since MBB have a centralized database; in this case, applying again online during the ban period will very likely lead to rejection due to the previous application.
The only possible way to avoid this is using a very strong referral (partner level), although there is not guarantee it will work. Some people also try to cheat the system changing emails/names in the application, however even in this case you may be detected.
If you have applied “informally” forwarding your CV via a referral, you may have not been reported in the system; if that’s the case, you will be assessed again based on the new documents uploaded. I would strongly recommend to apply via a referral and review your CV in this case before the new application.
Hope this helps,
