They are defined under DSDT or RSDT tables as any other ACPI objects
populating the ACPI namespace.

They can't be updated.

A DSDT table is not a static binary file. On most i386 or amd64
architectures, DSDT and SSDT are part of the BIOS.
The BIOS uncompressed and copyied them into main memory at the
POST stage since the ROM is too limited in size.

By the customer via BIOS updates obtained from the vendor.
