We have requirement to restrict 'Move to HR' until DOB and National id values filled by candidate

Summary:

Now we have upgraded to 25A oracle Recruiting cloud
Currently we are facing issue regards to Move candidate application from ‘offer accepted’ to ‘move to HR’ phase. Once candidate accepted offer one email send to candidate to fill Additional fields to provide SSN and Date of Birth details. Recruiters are moving application before candidate fill the additional information details, hence the application moving to HR without checking duplicate check. It is causing duplicate records in HR system.
Already DOB and Nations ID are required field.
Could you please suggest how to restrict 'Move to HR' phase unless until DOB and National id values filled by candidate
