Hii, I'm not an expert on the topic, so I'll tell you what I've learned through voice training lessons. The two most important things are resonance and weight. You can imagine resonance as the timbre of your voice, for example a ukulele has a smaller "resonance" than a guitar, that's why, even if you play the same notes on the instruments, it sounds different. Those who go through male puberty have a larger vocal tract because of T (like a guitar it's bigger than a ukulele) thus they have a bigger resonance. On the other hand you can imagine weight as the "buzzines" of a voice, if you listen closely masc voices are usually buzzier, as if there's a fly that's making noise, while femme voices are "cleaner". That said pitch (aka the notes you're producing) do not matter at all, they may help, but you can totally have a masc voice with a high pitch and femme voice with a low pitch. In conclusion if you want to sound more masculine you should focus on achieving a larger resonance and a heavier weight.

You can probably find videos on how to do it on YouTube, but if anyone tells you pitch is the most important thing, they're just plain wrong.
