You will have to mentioned the details in JEE application same as that in your identification proof as well as your class 10th 12th certificate. You can not put ABC in place of XYZ if your certificates have XYZ. So, I will suggest that do not manupilate the name and enter the correct information in th application as it is in your certificates, so that your application has no chance of rejection.
Hope this helps

Thanks!!
