Hello @AdamTyler-3590 Thank you for posting your concern on the Microsoft Q&A platform.
I see that you are configuring a VM to ASR replication and want to use exclude disk option which seems to be missing. There are certain limitations when it comes to excluding disks, listing a few:
- You can't exclude operating system disks or dynamic disks.
- You can't exclude a disk that's replicating.
- You can exclude disks only on VMs that have the Mobility service installed.
Can you confirm, if you have installed the mobility service agent on the VM?
Because, exclude options only comes when you go with Agent method and Agent is installed.

Hope this helps. Would be glad to assist further if you come back to us with an update.
