By far the best way of reducing noise on the UMO is by changing the stepper drivers to silent step sticks (I use the TMC 2100 version, and saw there is now a TMC 2130 as well), search for it here on the forums. You mention yours is an UMO+, I'm out of the loop in terms of what electronics board is in that, does it use the UM2 board w. integrated stepper drivers? (if so, you obviously can't change them).
As for changes in firmware if you were to change your stepper motors to 0.9 degree ones, all you have to do is double the steps/mm. for the axis where you changed motors.
You can do this directly on the LCD smart controller if you have one of those...

there is not exist 1.6 degree Nema motors.
They are 1.8 degree
