As on July 3rd, NIOS has postponed the Class 10 and 12th exams due to the Pandemic. The official notification doesn't release any new schedule but says that the exams scheduled to commence from July 17th stand postponed until further notice. So it is difficult to state whether NIOS will follow CBSE route. This might be difficult because CBSE and NIOS have different working patterns. So we might have to wait to hear from NIOS rather than speculating. Please watch out for official information regarding the same at the official website. Please also do not fall a prey to fake social media news.
