I don't believe that there are truly any "undecided" voters at this point. My chief hope is that Harris' strong performance will continue to stoke Democratic enthusiasm to GOTV, and that some of the people who may have voted for Trump in 2016 & 2020 will not feel motivated to go to the polls, especially if he's looking like a loser. Or, if they're a little more high-minded, simply write in some random name, as Mitt Romney supposedly did (he claims he "voted" for his wife Ann since apparently voting for a Democrat was a bridge too far for him).
There are definitely undecided voters and also voters who might change their minds. They doesn't have to be a great number of them, just enough to tip the scales. But, as you note, the more significant group are those who won't vote for Harris but decide they can't vote for Trump. While every switch is effectively two votes for Harris, any Trump voter who sits it out is one. That was going to be Biden's big problem...now it's Trump's.
