Lock folder on IPAD

Hi All,

I'm wondering if I can lock a folder with password on Ipad.

I need to distribute a group of Ipads between clients and I don't want they can use apps like iMessage, Mail, Cal and System Preferences.

I'm using a third party MDM, but they told me that Apple'nt exposed methods to do this, at this time.

Is there an alternative?

Thanks a lot who wants to help me,

G.
