Cisco Umbrella integration with MAX BR1

We are planning to deploy a number of BR1’s (over LTE) for a customers satellite sites. The customer is migrating to Cisco Umbrella and wants to know how we can integrate our LTE routers with Umbrella. I am assuming that we can set the BR1’s DNS towards the Cisco Umbrella DNS which will allow their traffic to be screened in the cloud. Has anyone else done this integration or do Peplink have any experience guidance on this integration?
