Hey, Thanks for reaching out to us.

Yes, you will be able to block the keyboard from predicting the next word as you type. The feature is supported only on supervised iOS 8.1.3+ devices.
To disable the predictive keyboard:

• Navigate to Policies-> iOS-> Advanced Restrictions-> Allow Device Functionality.
• Uncheck Predictive keyboard.
• Associate targets and save the policy.

Once the policy is successfully associated with the device, the predictive keyboard on the device will stop working.

Cheers!
