  For future reference, I got the answer by finding following statement in Driverpack_readme.txt in the DVD.  
I have a question regarding installing WS 2016 to R710 and DELL EMC Lifecycle Controller OS Driver Pack 17.12.00 that was published in late 2018.  May I ask if the driver pack should be installed after installing OS or during? Currently, my purpose is to upgrading Windows Server 2008 R2 on R710 to WS 2016. Actually, I may have to clean-install the OS. I know Dell does not support WS 2016 for the machine, and Lfecycle controller can't be used to install the OS until now. But late this year, Dell  published EMC Lifecycle Controller OS Driver Pack 17.12.00 that supports R710 and WS 2016. Thus, I wonder how to use the driver pack for the OS installation.
