Additional helpful note for potential future readers: if BIOS update does not solve issue, you can either keep this systemd service or add acpi_mask_gpe=0x6F as kernel boot parameter.

In my experience, this issue is reflected in 20-30% of CPU usage for the Linux kworker process or for the System process on a Windows machine.
Also, this approach is useful for any interrupts that might be hogging your CPU, use grep . -r /sys/firmware/acpi/interrupts/ to find out.
