You can certainly ask. However, based on what you've described, it doesn't seem likely to be granted. I suggest that you retain a locally experienced DUI attorney to see if you can do the community service hours instead. Best of luck.
The key phrase that raises a red flag for me when I read your fact scenario is when you say "I was never contacted by the probation department" after you were told to wait for a letter from them. This makes it sound like you waited a very long time without continuing to work on your remaining community service hours. I'm guessing this is the reason why it appears the probation department has filed a violation against you requiring you to serve jail time instead. If you had an attorney for your case, contact him/her immediately to figure out what your options are. Otherwise, you can use this website to contact a number of excellent candidates, one of whom has provided an answer here to your question. Give him a call to see what can be done after he is able to hear more of your fact situation.
Ask the atty who represented you to calendar an appearance to postpone the surrender date and give you time to work out with probation or sheriff (I think it is with the Sheriff) alternatives to jail. It seems to me that you think you can negotiate at the surrender date and time. If this is a correct assumption by me, please do be advised you are wrong and that the sherrif will put you behind bars! If you wish to contact me, please do so on seven zero seven, - 529-5219
