I have personally recently seen it at ELP, Laredo, McAllen, and Brownsville, plus heard stories of it at BUF and SAN to name a few. Sorry for the tangent.
Fresno just has FIS open a few hours a day in the evenings/nights to process a couple of flights from Mexico. I don't think there are any CBP personnel there during most of the day.
I personally think the risk is very small, no more than getting pulled over while driving. But perhaps driving to an airport without any international flights, such as Bakersfield, might be an option. OP, remember that TSA cannot detain anyone, so if they ask you about your immigration status, you can politely decline to answer and leave.
PS I've never heard of ICE at an airport. Also, is there a distiction between CBP and Border Patrol?
