New MAC address each boot

I’m currently using LibreELEC on my Radxa Rock Pi 4 SE and encountering an issue with the MAC address. On LibreELEC 10.0.4, the MAC address remains consistent across reboots, but after upgrading to the latest version 11.0.6, it changes with every boot. This inconsistency persists in the LibreELEC 12 beta build, leading to connectivity problems as my device fails to automatically reconnect to the router. Is there a way to prevent the MAC address from changing on each reboot?
