Cannot disable beep on boot

RouterOS General
1

When running
/system routerboard settings set silent-boot=yes
I get:
failure: not allowed by device-mode

Model: RB962UiGS-5HacT2HnT (hAP ac)

I am unsure what that means.

Because of this

routerboard: no

try this

/system/device-mode/update routerboard=yes

then poweroff your device
