You could use an -if- condition to exclude them. Stata will not resize a
graph so that it is smaller than the data space.

However, one of the important points of a boxplot is precisely that it does
show outliers. I would at least add a note that outliers at (specify values)
not shown, as people will automatically think that if there are no outliers
visible, then there aren't any.
