In general it can't be turned off. AFAIK there is some work in progress
to return conditional expressions in such cases, but I don't think it
is mature yet.
OTOH you can avoid specific questions by telling maxima the answer
beforehand: Use assume(a>0) to tell maxima that a is positive. There
are more examples how to use assume() in the manual.
HTH,
