Delete all MAC Address' in DHCP V4 filter Deny list at once

Hi,

Running Windows Server 2012 R2

Is there a way to delete all the MAC Address' in the DHCP V4 deny list using one Powershell command or NetSH command? I know I could do this via the GUI, but I am running a powershell script which adds a list of MAC address' from a CSV file. However as the list changes regularly, I need to remove all the deny list entries before add the MAC Address'

I've checked for some time but can only find a command to remove a specific MAC. 

Any help will be appreciated.

TIA
