Stopping LEDs coming on at boot

Other Hardware LEDs and Multiplexing
1

I have a short (14) strip of addressable LEDs that nearly always light up white/random when I power on my Nano.

Using Fastled.
Its not the code, as I use it all the time and the first command after setting up the strip in setup is to clear the LEDs (which works)

As soon as the code reaches setup and actually configures the LEDs + clear, then they go out as required.

Any ideas on how to kill this initial 'boot' illumination?

My only thought is another pin set up to switch a mosfet for the power... but that is a pain

As you know; code? wiring?

Try a 10K pulldown resistor on the Arduino pin.

Tried a 10k - still did it.
Just put a mosfet on the LED power. It was quicker
