Hello Aspirant,

Yes you will be considered eligible for JEE-Advance 2022 even if you have not scored 75% or more marks in class 12th, this is because for this year also the criteria of 75% has been waived off in the wake of pandemic and as you have 71% in your boards so you are eligible for JEE-Advance and then admission to IITs provided that you qualify JEE-Main 2022.
