Without a way to compensate, less backlash is better. With a way to compensate, it doesn’t matter.
No, you can’t adjust it this way.
Google “mechanical backlash” for a lot more detail. Basically, when you change directions, there is some small amount of error in the actual position vs. the desired position. If you know what this error is, you can adjust for it.
On a TAZ 6, the X & Y backlash are assumed to be very small. Older versions of Marlin assumed that the Z backlash was also very small and mostly got away with it (because for most of the print, Z was always moving in the same direction).
Versions of Marlin with backlash compensation (M425) can measure and adjust for it and at this point, it doesn’t matter how much you have.
