Yes, UPTAC (Uttar Pradesh Technical Admission Counselling) counselling does base its seat allotment for B.Tech programs on JEE Main ranks.  This centralized counselling process manages admissions to various engineering colleges (including government and private colleges) affiliated to Dr. A.P.J. Abdul Kalam Technical University (AKTU) in Uttar Pradesh.

A valid and qualifying score in the JEE Main exam is mandatory for appearing in UPTAC counselling for B.Tech courses.
UPTAC counselling might also consider other entrance exams (like CUET) for admission to non-engineering programs offered by participating institutions.
