Yes, from now PCB students can also do few selective type of engineering. As per 'New Education Policy 2020′ student can do engineering without even maths and physics as they are not compulsory from now . Recently, AICTE (All India Council for Technical Education) clarified that maths and physics is no longer compulsory for doing b.tech in few branches.

Students need to pass with minimum percentage of 45% in any three of the following 14 subjects to apply for admission in an engineering college if they want.

Those subjects are: Physics, Mathematics, Chemistry, Computer Science, Electronics, Information Technology, Biology, Informatics Practices, Biotechnology, Technical Vocational subject, Engineering Graphics, Business Studies, Entrepreneurship.

Hope this helps.
