If you are talking about the Staff Selection Commission registration, then you can't change your information once the form is submitted entirely. Now if you fill any other application form next year or after some months, then you can change it.
For more information you can consider contacting the regional office number which you can get visiting the link below:

I hope this helps. Wish you a great eve!
