Hey,
If you are a science student and you are not interested in MBBS, you can go for engineering. You can take a pick like computer science, mechanical, electrical, civil, and biotechnology, or just go for pure sciences like Physics, Chemistry, Biology, and Mathematics, and get yourself involved in either research or doing MSc at a later stage. Pharmacy, Nursing, Physiotherapy (BPT), Occupational therapy, and BAMS are some of the options if you want to be in the medical field but still do not like MBBS.

Agriculture, Food Technology, Biotechnology, and Environmental Science are four domains that are flourishing with a big scope. If you are into coding, then you can look at computer applications, data science, Artificial Intelligence/Machine Learning, or programming as some of the areas. Moreover, law (after science), finance, or teaching are also alternate routes for you like B.Ed., JRF, NET, or becoming a lecturer. The thing is to pick up a subject that suits your likes and talents, and the availability of scholarships and private courses makes it even more feasible.

I hope it helps.
Thank you!!!
