hi,

see you can choose mtech courses as per your gate paper from which you have attempted in gate exam, some of the iits or nits have some interdisciplinary subjects like embedded system, data science etc which is open to all streams students, now see the physically handicapped persons have different quota and cutoff score is low, so you need to choose the mtech course as per your interest.
