No. NTA clearly mentions that it will not change  any information entered by the candidates on its own after completion of application process under any circumstances. It is upto the Candidate to enter the correct information. Once the correction window has been closed,  NTA does not guarantee that any request for change in information will be entertained. And changing Category and swapping Candidates between Categories is not possible once the merit list has been released. You will be considered only under the Category that you have chosen.
