Yes, at an arraignment, the Judge maintains the right to "set" a bail applicable or in relation to the offense charged that could be more than the 100k already posted. 100K seems pretty high, which means that there were grounds either based on the severity of the charge, or if you were on warrant status for a lengthy period, to set it at 100k. My advice is to have a criminal defense attorney argue to keep your bond at 100k or argue for a tether monitor. Because 100k is a high bond, the judge may keep it the same if argued correctly and you do not pose any flight risk or danger to the community at large.
