Hi Shiju,
   The configuration "CONFIG_ACPI_APEI_SEA" is needed to manually enable?
In the "drivers/acpi/apei/Kconfig" file, the default value of ACPI_APEI_SEA is "y"

config ACPI_APEI_SEA
        bool "APEI Synchronous External Abort logging/recovering support"
        depends on ARM64 && ACPI_APEI_GHES
        default y
        help
          This option should be enabled if the system supports
          firmware first handling of SEA (Synchronous External Abort).
          SEA happens with certain faults of data abort or instruction
          abort synchronous exceptions on ARMv8 systems. If a system
          supports firmware first handling of SEA, the platform analyzes
          and handles hardware error notifications from SEA, and it may then
          form a HW error record for the OS to parse and handle. This
          option allows the OS to look for such hardware error record, and
          take appropriate action.
