Can I restrict apps on this tablet?

A

AC Question

Hi, I have recently been tasked with setting up a tablet for use in work. All that the managers need access to on this tablet are a couple of bookmarked pages, as they then login to check sales/etc. I have been asked to block off the rest of the features of the tablet so that they cannot just load Youtube/Twitter/Facebook when not busy.

My problem is that it is a badly restricted tablet - Lenovo A7600-F. So I do not even have access to Users within the Settings. It runs 4.4.2 and has no updates available (no surprise really). Unfortunately, I had no input into the purchase and as such could not recommend a specific device.

Any advice on apps/settings that may help block apps/restrict usage would be greatly appreciated.
