See some of the changes like this are going to account but its not made clear till now. The Education Policy in new printed form will be enforced and after the enforcement of the policy all the rules will be applicable. So anything for confirm can't be said but yeah! there will be no perfect major as per the NEP 2020 (as much as released). As this isn't enforced so you can major now but after the enforcement only all this rules of NEP 2020 will apply.

I hope my answer helps. All the very best for your future endeavors!
