Remove wireless info from macOS recovery mode on Apple Sillicon

I have a MacBook Air that has been connected to my WiFi network temporarily to configure it.

I've removed the WiFi netwerk in macOS and the Mac wil not reconnect to the WiFi upon restart.

But when I start the Mac in recovery mode, the WiFi network connection is back again!

And even worse, after restarting in macOS, the Mac automatically connects to the WiFi network.

Resetting NVRAM/PRAM does not work on these kind of Macs.

What can I do to make this Mac forget it has ever been connected to this WiFi network?

Two links to more info:

Revive or restore a Mac with Apple silicon with Apple Configurator 2 - Apple Support

This sequence isn’t documented anywhere I’m aware of, and I don’t presently have an M1 I can test this with.

Thanks for the info.

The link about NVRAM didn't have any info on WiFi networks.

The Revive suggestion however worked. After performing that step the MacBook didn't know anymore about my WiFi network.

I’m aware that the command article didn’t have the Wi-Fi info, but I don’t have an M1 handy to see what else might be visible within that same command path, if anything.
