I'm working on a tuner and want to get rid of sending false notes on long audio files, I need to extract the key in the first ~2 milliseconds, or ~100 samples for example.

is there a possibility to limit the length (samps/ms) for fzero~ ?

fzero-length-limit

What's the lowest frequency you want to detect?

Say it is 50Hz. That's a period of T=1/50=20ms.

To detect a frequency with fzero, you'll need a minimum of 1 period.

In 2 ms, you cannot detect any frequency below 500Hz.

usable portion to determine pitch could be anywhere,
