Obviously you can. After BSc Physics , you have a large number of options left to you. You can sit for lateral entry exams which will enable you to study B.Tech after your BSc.
The next option is to opt for MSc. Now for MSc you have a number of exams like IIT JAM , BHU , Central University exams etc with which you can get admission to premiere institutes in India. In JAM all the topics are not from class 11/12 , there are advanced topics like Quantum Mechanics , Solid State physics , Relativity , Electronics etc which you will get a detailed knowledge in your BSc Physics course.
After MSc in Physics you can go for MTech courses like MTech in Optoelectronics , Nano-Materials etc which can fetch you a job at government organization like ISRO , BARC etc.
You also have chances to do Integrated MSc-phD in institutions like TIFR , IUCAA etc.
Also you have courses offered by GATE Physics which will enable you to study in IIT's, NIT's and other institutes as well.
You have a lot of things you can do with it. Today you think of Engineering Physics as you get into the journey of BSc Physics you will get interested in other subjects. So study well and you can be a Engineering Physicist as well as many other kinds of courses.
I hope my answer helps you. All the very best for your future endeavors!
