B-LCD40-DSI1 BL_CTRL Not connected (R4 N/A)

We need to reset the display and would prefer to do sop with the backlight off to avoid it showing random patterns during the reset.

I noticed in the schematic that the BL_CRTL is not connected (R4 is missing), so is there a way to turn the backlight off and on again?

Thanks.

    I have found a DCS command in the board library for turning display on and off , so the BL_CRTL must be legacy and we can remove this track on next build.
