I came in Chile using my Taiwanese passport, it's been almost 10 yes and I haven't been able to save up enough to go back home

Now I would like to apply for Chilians nationality. I am not able to go back to Taiwan to obtain my certificado de antecedents which I can't get it through the embassy but the only way is to go back and apply in person. So, I was thinking... Since I also hold Paraguayan citizenship, could I use their certificate instead? Even though I entered Chile with Taiwanese passport.... Any idea?
