I have included Acronis resources into the Microsoft NCE PLM plan, but after provisioning, the Acronis tile is not available in the UX1. 


It is not supported to use PLM-basaed plan to sell other products in bundles.

This limitation is already mentioned in the PLM documentation:
A plan must include only products that belong to the same product line. Bundling products from different product lines in one plan is not supported.


Sell only one product line in the scope of a single service plan.
