Vocal fry happens when you hit the lowest parts of your range, but it's really just creaky voiced phonation which you can do anywhere in a register by lowering the amount of airflow and compressing your larynx to make the vibration irregular. I just checked on a pitch monitor and could do fem vocal fry at the exact same pitch as my normal speech (around 180-200hz, I don't have a particularly high voice but it's unmistakably fem).
If you do low register vocal fry, you may be able to get a feel for the muscles involved and try to incorporate that into your ordinary speech. I learned to do this for a while because I artificially gave myself very fem sounding vocal fry below a certain pitch so that it would sound like the low end of my range to make my overall voice sound more fem.
