No experience unfortunately.  But looking at strings in
DRIVERS/WAN/20221110.15030030/WwanNet/IntelWWANModemAuthenticator.exe
I see stuff like

DoFccUnlock
%s cancel...
%s: MBIM interface is not available, retry: %d
%s: Reach the max retry times
%s: QueryCommand FAILED
%s: Get challenge value from Modem FAILED!
%s: Send finial hash value to Modem FAILED!
DO result: %d
%s: No need
Set_INTEL_FCC_MBIM_Extension
%s: ulResponseLength is INVILED
Query_INTEL_FCC_MBIM_Extension
%s: QueryCommand FAILED hr: 0x%X
aVERSION: %ls



I guess you know the way from there :-)
