Hi Aspirant,

Hope you are doing great as per the question asked by you no you can't do B.TECH in other fields as you don't have maths in you 10+2 so you can only pursue B.TECH  biotech or biomedical. If you would have opted maths then you would be eligible for B.TECH CS, IT, MECHANICAL, AERONAUTICAL, ELECTRICAL.

Hope you found this answer useful.Stay motivated stay positive.

All the best!
