Change MAC address in macOS Monterey

I was unable to change the MAC address of the Wi-FI device on a MacBook Air (M1 2020) running macOS Monterey due to the following error: ifconfig: ioctl (SIOCAIFADDR): Can't assign requested addres.

By running the commands in following sequence I was able to change it successfully:

Turn WiFi device off
Turn the WiFi device on again: networksetup -setairportpower en0 on
Change the MAC: ifconfig en0 ether <mac-address-here>
Run: networksetup -detectnewhardware
