Yes, it is.

The following steps show how to move the services from Hybrid completely to Skype for business online:

Step1: Ensure that all the users are migrated from Skype for business onpremise to Online.

Step2: Ensure that none the Applications (Office Servers or any third-party applications) are dependent on the skype for business on-premise servers or made changes to make use of Skype for business online.

Step3: Modify the DNS records (externally & internally) and point the records to hit the skype for business online Services.

Step4: Disable shared address space on Skype for business online.
Set-CsTenantFederationConfiguration –SharedSipAddressSpace $false

Step5: Clears the contents of the DNS client cache.

Step6: Decommission the Skype for business onpremise deployment.
