Hello,
Yes, there are so many opportunities to switch your field to CS/IT. You should start by practicing coding on several competitive portals. If you do not have any background in coding then it will take you some time but after a period of time, you will be comfortable with coding. During this start learning Data Structures from the textbooks and online platforms. These are the basic building blocks for competitive and industrial programming. Start learning and understanding different algorithms from basics. Solve the algorithm based problem. If you want a job in this field then apply for different IT posts available in different sectors. If you want to pursue higher studies, prepare for GATE using standard textbooks.
All the best.
