While its possible that your attic has no visible ventilation system, its
extremely doubtful. Would consider verifying your assumptions before
seeking a solution.
An uncomfortable way is to go into the attic on a bright sunny day. Look
for daylight in the case of naturally aspirated ventilation. Soffit vents
are obvious outside, even if ducted, or idiotically covered with insulation
in the attic. Ridge vents and gable vents are obvious externally as well.
Same with turbine vents.
