I have a high-profile position for my employment. A DUI conviction will have terrible consequences for me. Will the prosecutor be willing to dismiss my charge of driving-under-the-influence based on my high-profile position?

No.  In California, the prosecution office for a county will not take into account a person’s status or position when deciding to charge a person with driving under the influence.  In fact, high-profile cases are often more rigorously prosecuted because of the attention they receive.
