Hmm, I do not observe this on:

Handle 0x000B, DMI type 0, 24 bytes
BIOS Information
        Vendor: LENOVO
        Version: N1MET37W (1.22 )

...
        BIOS Revision: 1.22
        Firmware Revision: 1.15

Handle 0x000C, DMI type 1, 27 bytes
System Information
        Manufacturer: LENOVO

        SKU Number: LENOVO_MT_20HQ_BU_Think_FM_ThinkPad X1 Carbon 5th

I wonder if we have different configs...
