Using host networking for Windows: workaround?

Hi, I see that the host networking option is not available for Docker Windows.
I’m runnng pihole in a Desktop Docker and I need to allow network traffic to flow between the docker internal network and the host network.
reason: in pihoIe I am not seeing the hosts (devices) on my network, only the router itself; broadcast traffic is blocked by subnet.
I have been through pihole forums and support and I need to create a new bridge without NAT
can someone give me some guidance on how to accomplish this?
or any other ideas on how to resolve this?
I am using docker engine v19.03.12
Windows 10 Pro 2004 (latest at time of writing)
many thanks for your time
Pete
