Disable mDNS in Edge 89.0.7774.63 for many Windows 10 machines

Question

I'm in an environment where I have to tightly control accessible logical network ports on all cyber assets. After installing the new edge, I noticed that when running, it opens UDP 5353 for an mDNS capability. I found the flag (#enable-webrtc-hide-local-ips-with-mdns) to disable that, but I need to do that for all machines and all users and I really don't want to have to visit each machine one at a time if possible.

Is there a registry setting, PowerShell command, etc that I could use to affect that change across all of the workstations?

pfranson&nbsp;Hi,make a shortcut on your clients' PCs pointing to this:"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --flag-switches-begin --enable-features=WebRtcHideLocalIpsWithMdns --flag-switches-enddeploy that shortcut using any management tool you use, sccm, intune, group policy etc.that will launch Edge with that feature.
