Thank you for posting in Microsoft Q&A forum.
I did a quick test about this, if I set "Configure BranchCache"=Yes and "Enable BranchCache"=Yes, the BranchCache Service installed and the BranchCache is enabled on client.
If I set "Configure BranchCache"=Yes and "Enable BranchCache"=No, the BranchCache Service installed too but the BranchCache is not enabled on client.
So set "Configure BranchCache"=Yes make the BranchCache Service installed.
