You cannot apply for B.Tech courses after appearing for JEE Mains 2022 1st session till NTA announces results after all the sessions. After announcing the results, the admission portal will get open in the official website till then you have to wait and prepare for further sessions and All the Best for your further sessions.

For NITs you should have a percentile of around 97 percent in JEE mains for open category and for any engineering college in India for a open category student it is mandatory to get a percentile of over 90 to get into software based course in the college.
