Sorry to be the bearer of bad news but there is no evidence either biblical or secular that has disproved the validity of 607 BCE. I have been studying this subject for nearly forty years and have read all published attempts to dissprove 607 BCE only to find that on a critical analysis none of these attempts have succeeded. The most recent attempt has been by Carl Jonsson who has acquired a reputation of being a competent chronologist has claimed in his most recent work that there are at least seventeen lines of evidence that disprove 607 BCE. However, competent biblical scholars have shown that such a claim is fanciful and is not supported by either the biblical or secular evidence.
This does not mean that 607 BCE or any other date is not capable of being falsified but at this point in time there is simply no evidence that disproves the validity of 607 BCE for the Fall of Jerusalem.
