Most modern mainboards don’t even support ACPI S3/S4 anymore. The ACPI spec is pretty badly written and most implementations were flaky in some way. So when ACPI S0ix (aka Modern Standby) came around the old states were essentially abandoned.
Of course S0ix is less a hibernation and more kindly asking the OS to turn off the screen and consider using fewer resources.
Its called “modern standby” or something, and is the main option for suspending windows laptops I believe
