Hi Aspirant,
Hope you are doing great as per the question asked by you yes you can certainly do B.T.E.C.H IN CS and I.T in I.T.I as both are graduation courses which are usually done after class 12 to make your career in respective field. But i would recommend you to do B.T.E.C.H as it has more value as compared to I.T.I.
Hope you found this answer useful.Stay motivated stay positive.
