how to reboot machine using DSC with ARM template

My scenario is that I uses ARM template to provision a redhat VM, in order to configure my VM, Linux DSC extension is used in template. During configuration, VM needs to reboot a few times. How can I achieve it? For Windows DSC, a meta configuration RebootNodeIfNeeded has to set to true, and a global varaible $global:DSCMachineStatus has to set to 1. In Linux DSC, I could not find solution. First I can only apply meta MOF or MOF file, but not both together. Also I could not find the global varaible $global:DSCMachineStatus .
