If you turned 2FA on within the last two weeks, you can disable it by using the link in the confirmation email. This is the only way.

If you have had 2FA for longer than two weeks or you just created a new Apple ID, you can't disable it.

Two-factor authentication for Apple ID - Apple Support

In settings u should find 2 factor authentication just switch it off :)
