SV3C camera settings

Got a SV3C camera to try out for a couple cameras here.  Got Zoneminder working ok without much trouble.  Now trying to figure out if I can turn off the IR LEDs and use a separate illuminator to keep the bugs/spiders away from the camera.  The camera is B01POE-3MPL-A.  Have noticed the picture of the unit I got on the quickstart guide (marked "A series") doen't quite match my unit.  Going on line for the manual the config screen in the manual has a lot less settings than mine and doesn't explain them in any detail.  Anyone know how to turn off the IR LEDs but keep the B/W low light capability?

Thinking there might be a setting in the GUI of the camera to do this.  Lots of times though the switch is integrated to the night / day modes.  It is only two wires to the lamps and you can just disconnect them disassembling the camera.

Manufacturer confirmed that it isn't possible to shut off the IR LEDs and stay in low light B/W mode.
