Ontario PNP noi and ITA processing in parallel

I received Ontario PNP Noi and 2 days latter I received ITA. I know people will say if you get ITA why would you bother with submitting for PNP noi. But if I don’t feel confident about my documentation and need to submit PNP noi is that possible? Do I need to chose between two or I can submit for processing of both PNP Noi and ITA?
