No. California's 10-year lookback period applies to standard Class C licenses. Most commercial driver's licenses are subject to the Federal Motor Carrier Safety Improvement Act of 1999 (MCSIA). That act requires a DUI to stay on a commercial driver's record for significantly longer than ten years. But this only applies to the driver's commercial license. After ten years of clean driving, the driver's rates for driving a non-commercial vehicle should come back down.
