Disable only when disabled in BIOS or the firmware don't support this capability. If the firmware has this capability, read BIOS configuration data in function 4 using ACPI API and send GRP_REGULATORY_LARI_CONFIG_CHANGE_CMD to the firmware. Any error while reading BIOS data results in enablement of china 2022 regulations.
