Hello Aspirant,
Yes of course you can get admission in any of the NITs/IIITs for their engineering courses if you have passed your class 12th in 2019 with 65%, provided that you must have appeared for JEE-Main. This criteria is only valid for this year because of COVID-19 and it is not sure whether this will continue for next academic year or not. The reason being is Our hon'ble Education ministry decided to waive off the percentage criteria of class 12th for admission to engineering courses of NITs/IIITs. Also note that this is your final attempt to appear for JEE-Main because you had passed your class 1th in 2019.
I hope this information helps you.
Good Luck!!
