CA -> Nevada State Income Tax Filing for next year's tax filings.

I was a student in Illinois earlier this year, then went to California for a period before coming down to Nevada and earning income there. I filed resident CA state tax last year, and have a CA drivers license. Is it possible to declare NV residency for when I file my taxes for 2020 in 2021? If so, does this mean I do not have to file any State tax in 2021 as NV does not require it? Please let me know if I can provide any addition information that would be telling.
