Can I use race boots for regular resort skiing if I'm an expert skier but don't race?

Technically yes, but it's rarely the best choice. Race boots are optimized for the specific demands of racing—high-speed carving on groomed snow with maximum precision. For general expert resort skiing that includes moguls, powder, trees, and mixed conditions, a high-end frontside or all-mountain boot will be more comfortable, more versatile, and nearly as precise on groomers. Race boots are noticeably worse in any off-piste or variable snow condition.
