Manage led on an Sophos XG 106 reinstalled with OPNsense

[renow]

Hi,

I have installed OPNsense on an old Sopos XG 106 FW.
Everything si working well.
Network interface, power and HDD leds are working too.
Status led is always blinking and I'd like to fix it when os loaded and maybe blink on error.

So I'm looking for a solution to manage leds.
I've seen apuled package, but /dev/led doesn't exist...

Thanks for your help.
Regards,
Renaud.
