Yes you can do this by going to Configure> Open the Network Policy> Got to the Router Settings tab> Network Allocation (left hand side menu)> Edit the network assigned to the VLAN you'd like to have the reservation on or create a new one> Enable DHCP if it isn't already enabled> Drag the "Exclude at start/Exclude at end" bar to encompass the address you need to reserve. We won't be reserving an address for a specific MAC address, but the address won't be handed out automatically to a client so it will be available to be manually assigned to the device.
