Yes, you want a custom shader. The common toon shaders are uts2, poiyomi, silent and liltoon. Maybe a couple i forgot. You could just slap vrchat's built in mobile/quest toon shader on it first and see how that looks. Standard shader is just really bad for catoony avatars, even furry stuff is better flat lit with a toon shadow ramp.

also the fur settings in several of those shaders might be worth trying on it.
