Is it possible to be a worshiper of the true God without being reached/evangelized?

Upon reflecting on the answers to this question, https://christianity.stackexchange.com/q/80507/61679 , I noticed that Romans 1:18-20 leaves interpretative space to still think there is hope for the unreached/unevangelized. | Romans 1:18-20 ESV | | - | | For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who by their unrighteousness suppress the truth. For what can be known about God is plain to them, because God has shown it to them. For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse. | If my interpretation of what Paul says here is accurate, then it seems to me that the unevangelized would be able, at least in principle, to infer the existence of the Creator from creation, by exercising some elementary, layman, common-sense version of [natural theology](https://plato.stanford.edu/entries/natural-theology/) . If this is the case, then why would it be unreasonable to think that at least some of these unreached/unevangelized individuals would be able to react favorably to this insight, by becoming a worshiper of said Creator? Another way of phrasing my question is as follows: Is it possible for a human being to become a true worshiper of God by inferring His existence based solely on natural theology? Does this view have a name?
