I've got 91.8 percentile in Jee mains 2019 I belong to OBC category. Can I get CSE branch in IIIT Una in Himachal?

Indian Institute of information technology Una (Saloh), popularly known as IIITU, was established in the year 2015 by the Central government of India and MHRD under the Public Private Partnership Act. MHRD, Govt. of India, Govt. of Himachal Pradesh, HP Transmission Corporation Limited, HP Power Corporation limited act as partners to the institute.NIT Hamirpur has been given the responsibility to mentor IIITU. Presently, IIITU is operating from the NIT Hamirpur campus until its new campus is fully set up in Una.

Unfortunately it is difficult for you to make through IITU as its previous year cutoff was around  22000 and according to your percentile it will difficult to make through it in first round.
