It cant I tried few known methods for .cab files weeks ago and failed I suppose it can only be integrated
I tried to integrated "DISM.exe" /Image:%WIM% /Add-Package /PackagePath:%UP% I get an error An error occurred trying to open - Windows6.1-KB974333-x86.cab Error: 0x80070002
Check the files inside the cab with those already on your computer, I think you will find the files are updates to the same as those in the cabs (if you have installed all the applicable released updates).
Install cab updates for example : put your updates in 'Updates' folder in drive 'C' and make '01' folder in drive 'C' run this command in 'CMD' C:\Windows\System32\pkgmgr.exe /ip /m:"C:\Updates\KB973874.cab" /s:"C:\01" /norestart after restart you can delete '01' folder from drive C
I created 2 folder in drive 'C' updates and 01 and KB974333-x64.cab in updates I get an error 0x80070002 The system can not find the file C:\Windows\System32\pkgmgr.exe /ip /m:"C:\Updates\Windows6.1-KB974333-x64.cab" /s:"C:\01" /norestart
