Dear student,
YES you will have the fee reimbursement in the first year b.tech as it is the new course you choose and through all the counselling channel and process you are enrolled as new student so your scholarship and fee reimbursement form will be filled as a new student and the amount you will receive will not be related to one you got in B.Sc course.
And no you can not refund you scholarship back to the government.
