Not spoofed Mac sent to router?

Good day
After read this

the better option is to use another wifi card. The question below is related to Qubes but I believe that could be also to other OS.
Going to network connection of a sys-net I see the real MAC address is detected in the “device place” also when it is spoofed. Could be it sent to router or is here because in a way the VM has to have a wifi card attached?

Yes

About this?
