Yeah. There are some basic service tasks that are the same as for ICE cars (brakes, suspension, diffs, exterior/body panel checks, air filters and other stuff that's unchanged), and most of the electric drivetrain and battery stuff is not really serviceable - there's software-based diagnostics and parts replacement. But since it's all mechanically much, much simpler than a traditional engine and drivetrain there aren't really any complex parts to service and fix in place on the car that would require extensive training.
Working with high voltage systems is the one important new thing to learn, but that's less complex training and more precautionary "don't touch anything orange-colored unless it's been powered down for a while and even then only when you know exactly what you're doing".
