Yes. Archeology means never having to say "never". Just because we haven't found evidence of something so far, doesn't mean it won't be found in the future. Absence of evidence is not evidence of absence.
I remember a Bible show with an episode narrated by Leonard Nimoy. Someone had found a small pillar with the inscription “a Jew worshipped his God here.” Which coincided with travel by Moses.
If someone were to use that as evidence that Moses left that inscription, I would point out to them that at the time of Moses, no one was yet called a Jew. That term only came into use about 900 or so years later, after the exile of the southern kingdom of Judah. When they returned to the land it was called Judea and the inhabitants were then called Jews. During the time of Moses they would have been called Israelites.
You show knowledge of the topic. I think the writing was by someone else about Moses to commemorate the place. But true, the name for the people wasn’t current for a long time.
So many episodes of In Search Of and others that I can’t find it.
I remember the line distinctly.
Of course I am not responsible for the line, Nimoy, or the show or the series.
