The Navajo number is not much different from how deep blue cities vote and if they are also deeply opposed to Trump it doesn't prove anything (details linked below). The impression I'm getting from you and everyone else yelling fraud is that you're just certain that it must have occurred but don't know how it did. There are an awful lot of contradictory statements being thrown around, but nothing beyond a couple of anecdotes of a few voters that are suspicious. Asserting that we need more election integrity but not explaining what was fraudulent and how the fraud could have occurred at a scale of 10s of thousands of votes is irresponsible and very damaging to our democracy.
