In python, with a NDarray of uint8s, how could I iterate over the array, and at indexes contained in a secondary NDarray, swap the LSB of the integer with the value from a third NDarray, containing only binary values, assuming all arrays have correct number of values.

What have you tried? Ignore the secondary array for a minute; do you know how to swap the LSBs unconditionally?

Please give some example input and desired output so we have material to test possible answers. It doesn't need to be your real data; just a handful of numbers would do.

"iterate over the array" - If you're talking about using a for-loop, that's actually an anti-pattern for NumPy. You should use array operations instead. I can show you once you give an example.

Specifically, the details I'm looking for are: 1) Are the indexes given as ints (or tuples of ints), or as a boolean mask? 2) What do you mean by "binary"? booleans? Reference: minimal reproducible example
