Navamsa choice- Birthtime issue

Hello guys so I have a small birthtime issue where I have 2 navamsas

I'm unable to select through rectification

I could be pisces navamsa or aquarius navamsa

Can anyone please help me 🙏🏻

I tried using pranapada lagna and d81 kunda method but It gives possibility in both navamsas. I am 24 so no marriage event or relationship to use for dasa based rectification also
