I am a current student at IET Lucknow, and I can assure you that IET has enough provisions for scholarships if you are really a deserving candidate. The top scholarship offered is the UP Post Matric Scholarship. To be eligible for this scholarship, your family income should be equal to or less than INR 2 LPA. If you have any questions, you can go to the Dean’s office or to this link https://scholarship.up.gov.in/.
You also need some documents to apply for the scholarship. You can refer to the list given below.
