Sure, you can if the Devices are enrolled Via DEP. You will have an option to enforce this in DEP Policy(Admin Tab->DEP->DEP Policy)
Yes, you can. We you can lock them from removing the “Device Administrator” rights. He has to remove this permission to uninstall Hexnode. This option will not be available in generic devices. The device has to be ROM/OEM type or rooted or from supported manufacturer. You can do this from “Policy->Android Settings->Restrictions”.
Thanks and regards
