Presently in India, no university is allowed to offer any professional course including Engineering via distance education mode. Hence i would like you to check with whomsoever is offering this course to confirm acceptance by UGC for this. Best wishes to you.

it's indeed great to know that you are interested in doing your graduation in engineering after completion of your diploma. At one place you are saying via open meaning distance education and at another place you are saying part time. These two are different. Engineering graduation vua distance education is not allowed in India. But part time is allowed. Hence seek clarification from college about this issue before paying fees etc. Best wishes to you.
