Removing gnome-software from Silverblue

I want to remove gnome-software from Silverblue. I observe downloading in the background from my net speed monitor even though I have turned off auto-updates. On Workstation I have completely removed gnome-software and packagekit so that this automatic updating does not happen. I want to do the same on Silverblue. But;

rpm-ostree override remove gnome-software

does not remove it. What is the correct way to remove gnome-software from Silverblue?

Thanks in advance.
