Enabling ABM at the vCenter level - Non NTFS VMs

If I enable ABM at the vCenter level, I'm guessing this applies ABM on all VMs connected to the vCenter server. How does this handle Linux VMs? I know that it only works on NTFS drives so if it detects that the VM is running something other than NTFS, does it just keep using CBT and not apply ABM?

Or if I have a mixture of VMs should I enable it on a per VM basis?
