#1 
/dts-v1/;
/plugin/;

/ {
        compatible = "radxa,rock3a";

        fragment@0 {
                target-path = "/";

                __overlay__ {
                        leds {
                                compatible = "gpio-leds";
                                led_user: led-0 {
                                        /delete-property/ linux,default-trigger;
                                };
                        };
                };
        };
};

Tested on armbian kernel 5.18.2. Use command sudo armbian-add-overlay rock-3a-disable-led-heartbeat.dts to install this overlay.
