Hey I have a suggestion if you're still wondering!
So this method actually helped me a lot.
So start by tilting your head downward and by humming in your regular pitch. Then slowly raise your head while continuing to hum. And finally tilt your head back down. And now your voice is deeper than before you started the process.
This helps your vocal cords to become deeper. You can do this as many times you need until you're satisfied. But please be careful and don't do it too much. The first time I did it, I felt really proud. And the day after my throat hurt. I'd say that doing it only once actually lasts a couple hours!
