Latitude 5300 SMM Security Mitigation (BIOS update)
How guys,
We have a large fleet of the 5300 when trying to update the BIOS via SCCM, it sits there and freezes.
When disabling SMM Security manually you are able to update the BIOS without issue, we need to automate this though.
I have tried the latest cctk tool 4.3.1 running the command cctk.exe --SmmSecurityMitigation=Disabled, returns with (There was an error setting the option 'SmmSecurityMitigation') when running =Enabled (is already Enabled)
Does anyone know of a fix coming out for this, I thought I read somewhere that this version of the tool did have a fix for this issue.

i have the same problem with 250 latitude 5300. I cannot install Thuderbolt port update unless I disable SMM mitigation in BIOS. the CCTK command "SmmSecurityMitigation = Disabled" does not work highlighting the error "There was an error setting the option 'SmmSecurityMitigation'". We cannot go and do the modification in the BIOS of each pc; for now we have suspended all updates
