Using cloudmonkey, pass args: (note lowercase) details[0].key=nicAdapter details[0].value=vmxnet3
If it's not working, check if the version of CloudStack supports this feature (overriding the default nic adapter setting using template details). Alternatively, you can pass this while deploying the vm using deployVirtualMachine API.

It does not seem to be working even though it seems to be accepted via the API.
