How to change WiFi MAC address on Debian 9?

Question

linux

What I have already tried:
1) macchanger
2) ifconfig eth0 hw ether XX:XX:XX:YY:YY:YY
3) /etc/network/interfaces
Always the same: it turns out to change the MAC address only once, after connecting to WiFi, and if you reconnect, everything is reset to the usual, default address.
The goal is to always have a different MAC address. Both during scanning of networks and during connections to them.
What could be the problem? Could this have something to do with the hardware itself (all this happens on a laptop)?
