Hello There Amit hope you doing well , see if your rank is under 1-2 lakhs there is a chances to get some gftis or dtu or ipu but at that point you have to compromise your branch but if your rank is 2-5 lakhs you will have less possibility to get gftis dtu or ipu but there is still a hope that some university take out the application after the counselling as some student leave their college and they have vacant seat but in this case you have to be active and search for every applications of that colleges which you want as the form is only available to specific university website but you have to wait till December for this process you can atleast take an admission in private university and if you are lucky you can change your college in December if you get accepted

you can check JEE Main Rank Predictor and you will get a list of college which are available under your rank
