Ever more connection (Ethernet) icons, need to stop them

I've done a vanilla LinuxCNC 2.8.4 Debian 10 Buster PREEMPT-RT ISO installation, which basically seems to work fine 'out of the box'. There's a niggle though, in that on every boot up I get an additional 'Connection Wired Connection 1 (802.3 Ethernet)' icon appearing at the top of my desktop. It's getting out of hand, see screenshot, and I can't ignore it any more. How do I kill this behaviour?

It might not be what you want to hear but I solved this by upgrading to bullseye but today it makes more sense to move to Bookworm because linuxcnc is in their repos.

I believe there is another solution

Brilliant, as a Linux beginner I didn't even know it was called the nm-tray. All I needed was the sudo apt-get remove nm-tray. I'll be lookng at the other tips in that thread.
