Unfortunately, Bermuda grass is so closely related to St. Augustine grass that there is nothing that will remove Bermuda from St. Augustine and not hurt the St. Augustine as well. In your situation it is recommended to spot treat the Bermuda with a non-selective glyphosate product and kill it directly, then replant St. Augustine in those areas.
