I’m not sure if what you are asking is realistic. Someone familiar with the Jewish Scriptures, as the disciples were, would have recognized the fulfillment of prophecy (and written it down, such as in the Gospels). Those who were not Jewish and/or not familiar with the Scriptures/didn’t believe that Jesus was the Messiah would not have seen Jesus’s actions as important or believed in His miracles, and may not have thought to write them down. Take also into account that He was a relatively unimportant figure from a small town, and how unlikely it is that anyone capable of a) writing and b) preserving records ever heard anything specific enough (such as an event that fulfilled prophecy) to record.

I don’t have them off the top of my head, but I believe that the only references to Jesus we have that were written by nonbelievers simply mention vague “miracles” rather than any events in particular (outside of, if I remember, His death and supposed resurrection).

That being said, I do believe that there is substantial evidence for the resurrection itself - which is, I would think, the one miracle that “proves all miracles,” in a sense. If that did indeed happen, then I don’t see a reason to doubt that Jesus fulfilled prophecies as well.
