Changing Mac address of Client Mode

I am using OpenWRT to connect to a Hotspot service in Client mode (which is the only one that works with it).

Can someone tell me if there is a way for me to change the Mac Address presented to the hotspot service I am connecting to?

I assume that client mode emulates a wifi adapter and there might be a setting somewhere but I can't find it in LEDE.

Thanks in advance

You would add an option macaddr in the wifi-iface section.
