No! The strict eligibility criteria for JEE is that you need to have a 10+2 from a recognized board with 75% marks in it (this year the barrier is removed due to covid situation). So you won't be able to go for JEE MAINS with NERIST certificate.

You can study for NIOS and then you can apply for JEE MAINS.
