Issue with Required Last Name Field During Participant Registration

I have encountered an issue with participant registration for my upcoming event. Although I did not select the option to require participants to provide their last name, Zoom automatically requests this information during registration.

As the event organizer, I do not need this information, and my participants should not be obligated to provide their last name. Could you please explain why Zoom is enforcing this requirement and how I can disable or remove this field from the registration form?
