Hello TapPearson,
Unfortunately the Interface Description is provided by the manufacturer and Windows allocates the "#" for differenciating same model and brand interfaces.
What can be change is the Friendly Name of the adapter with:
Rename-NetAdapter -Name "Ethernet" -NewName "ManagementAdapter"
Reference: https://learn.microsoft.com/en-us/powershell/module/netadapter/rename-netadapter?view=windowsserver2022-ps
There are some details provided by comunity experienced users, that went through the registry and it seems that mainly the Interface Description is allocated in these paths, but also in many other places of the registry, so if there is a dependancy you would need to us the Find option in the registry to locate all the places where a Interface Description is mentioned and change for the same. This process is highly not recommended but provided as orientation:
The main regsitry chain for the settings is here:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkCards\2\Description
and
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\NetworkCards\2
