Is there evidence to support Deuteronomy being written before King Josiah?

this previous question asks for evidence that points to Deuteronomy being written during the reign of King Josiah. A lot of modern scholarship today suggests that Deuteronomy was a much later work, produced in a much later time period. So what evidence is there that points to Deuteronomy being written before this time? I am willing to accept that Deuteronomy may have some redactions and changes, but lots of liberal scholarship points to it being a much later text, with no relevance to Moses or the first four books of the bible at all. Any general answers that highlight evidence for an early date for Deuteronomy / before the reign of King Josiah are welcome. This question may also naturally lead to the question of authorship, so if that isn’t too broad, feel free to include that in your answers as well if you deem it appropriate.
