Logic Level Converter Question

I just have a quick question about the bi-directional logic converter. I am planning to use these to boost the 3.3v digital signal from a teensy 4.0 up to 5v to control WS2812 leds. My question is since I only need data going in one direction will this work without hooking up the 3.3v input? It would make my life a lot easier if I don’t need to run a wire out to supply the board with 3.3v.

Unfortunately, the mosfets need the 3.3V input to work correctly
