Hello Sunil,
I am afraid that your rank of 53k is not enough for you to secure seats any of the mentioned IIITs in any branch even with the EWS category. As you may know, these IIITs are counted in old IIITs and are well established. They are very much in demand and generally close around 30k. With EWS, you can expect them to close around 36k max. I would suggest you look for other newer IIITs as you might stand a chance till CSAB round. All the Best.
Thanks
