I dont know what you are making...but if it is booleans you need...then you will have to go Mesh>Smooth and divide it maybe a couple of times (ie do it again)..this will leave the geo PERMANENTLY smooth mate...so make this decision wisely..
Not entirely. If you have the history on you can go into the smooth node in the attributes and adjust the continuity back ot 0 to get rid of the smooth.
