How to get rid of phantom, orphan network interfaces on macOS 15?

I have some ghost/orphan network interfaces on my Mac Mini M1 2020 (macOS 15.1) that I would like to clean up. They appear in several places, such as in the **Internet Sharing** System Settings pane, as well as in the Terminal output of networksetup -listallhardwareports. Running the command below reveals these network interfaces, several of which no longer physically exist:

networksetup -listallhardwareports | awk '
/^Hardware/{sub("Hardware Port: ","",$0); n=$0}
/^Device/{sub("Device: ","",$0); d=$0}
/^Ethernet/{sub("Ethernet Address: ","",$0); m=$0}
/^$/ && n!="" && m!="" && d!="" {
  printf "%s\t%s\t%s\n",d,m,n
  n=m=d=""
}' | sort

### Output

en0	14:98:77:64:11:0d	Ethernet
en1	14:98:77:5a:8b:1b	Wi-Fi
en2	36:32:32:20:15:00	Thunderbolt 1
en3	36:32:32:20:15:04	Thunderbolt 2
en4	82:03:9a:33:94:72	Ethernet Adapter (en4)
en5	82:03:9a:33:94:73	Ethernet Adapter (en5)
en9	00:e0:4c:68:13:10	USB 10/100/1000 LAN

In my case, en2, en3, en4, en5 and en9 do not exist. I would like to purge them. I have tried deleting the **NetworkInterfaces.plist** plist using

sudo rm /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist

However that does not make them go away. Related question with no answer: https://apple.stackexchange.com/questions/461089/how-do-i-get-rid-of-old-orphaned-network-hardware-ports-under-macos
