Hello Krish, 

You cannot change the address  when it is officially on the admit card. But no,  this will not get you disqualified from the exam in any way so don't worry about that. What you can do is fill correction form and submit with the relevant authorities (aadhar centres) . 

You can get further details about aadhar card discrepancies here : medicine.careers360.com/articles/neet-know-aadhaar-card-requirement-for-neet-application-form

Hope this helps  :)
