Company folder should be blocked in the Data Manager

Hai Experts ,

We need to block the company folder access in the Data manager while doing flat file upload in the BPC.

Currently we assinged  USER task  profile  to users  AccessContentLib, CreateJournal, Execute, BPFExecution, PostJournals, ReviewJournals, SetWorkStatus, SubmitData, UnpostJounals, eAnalyze, AddComment, CommentReport

When the user click the Destination file from Manage data , the Company folder & Private publication is now opening .

But we need to restrict the Company folder for USER access profile .We need to open only the Private publication for the user access*

We need to do any setup in the User Task Profile in BPC admin.

Please suggest

Regards
