Is it safe to drive my car if the check engine light comes on?

Hello, it is best to have it checked as soon as possible by your local Toyota dealership, since a 2021 should still be underneath factory warranty. Check your fueling cap to make sure it is tightly secured. Beyond that, take note of any driving concerns - does it seem normal? Or does it run abnormally? If it's abnormal, then I would not drive it at all. If it seems to be performing normally, you could drive it cautiously until you can have the vehicle checked.
