I am currently pursuing Btech 1st year in CSE (AI/ML) but not getting much interest in coding and stuff. Will you suggest me to drop out engineering after 1st year and take up BBA as I have to prepare for CDS exam after my graduation?

Hello,

If your main goal is to prepare for the CDS exam and you are not interested in coding, switching from Btech (CSE) to BBA can be a sensible move.
BBA is lighter academically and gives you more time for CDS preparation. However, before dropping out, make sure you’re clear about your decision and have confirmed BBA admission — so you don’t lose a year.
