I think it might do, but a safer option, is to use the slave module, it uses a standard M12 , its very easy to unscrew, i replaced with a standard NIR lens and it worked great with IR led torch, only issue is not rtsp stream yet with slave camera. This way no risk of damaging main camera unit. Also very easy to slightly unscrew lens to get macro mode.
ive heard the G3 housing and lens is trickier to take apart than the Git2, I found the slave camera very easy to take apart, and a left over M12 CCTV lens fitted perfectly. so I can record IR with a set of IR LEDs for illumination, and just unplug slave when I want to use G3 normal lens
It would be great if viofo/gitup made a bodycam, as they are just like action cameras but with IR
