You can. There is literally "furry preferences" option which allows player to set all furries or specific race to:You can't affect the furriness
"disabled" (replaced by human race)
minimum (furry ears, eyes and attachments like horns, wing etc)
lesser (same as minimum + possibility of them having furry limbs, breasts and genitalia)
greater (lesser + sometimes furry skin/fur and face)
maximum (every single bodypart is furryfied)
However, this options don't apply to persistent NPCs such as Brax
