Hi aspirant

There are different eligibility criteria for different college category i.e diiferent for NITS through JEE mains , architecture colleges through JEE mains paper2 or JEE Advance.

You won't be eligible for NITs/IITs due to low percentage in boards.

You can check the detailed eligibility criteria here:https://engineering.careers360.com/articles/josaa-eligibility-criteria

Also if you are looking for state engineering govt. colleges of your home state then you should apply for state counselling.

You will get all those colleges through state counselling on the basis of JEE mains score.

All the best.
