If you meant pursuing BTech along with BSc, then yes as per recent UGC guidelines candidates can now pursue two degree courses simultaneously, but the only condition is one has to be done through regular mode and another through distance mode, in your case as BTech is a professional degree and can't be pursued in distance mode as the same has been corroborated by the Supreme Court, you can pursue Btech in regular mode and for BSc you can enroll in any open university such as IGNOU, NSOU, BRAOU to name a few.
