There is a prescribed way of nail grooming for classical guitar

there are fingerpicks that you wear of all sorts (including stick on)

then there is just growing your nails out just long enough for you to fingerpick comfortably.

I think Tony Covered some of this on an AT episode, though I am not sure which one, and I am not sure if it was the main topic.
