Same mac address on virtual bridge after physical clone

Wondering if anyone knows how to avoid the following.

I'm cloning a physical Arch instances with clonezilla. The instance has a systemd virtual bridge interface which works well.
When I deploy a new instance from clonezilla the virtual bridge has the same mac address as the parent, so I get IP conflicts. I can manually fix this by deleting the virtual bridge and creating a new one with a different name, but this is painful at scale.
I'm hoping there is a way so the mac is not persistence or that it is determine from the mac of the physical interface.

On centos I recall there is a udev rule to control or reset this, but I do not see it on Arch.

Thanks in advance.
