It depends - generally, the answer is no, but there is a Toon BSDF in the Cycles shaders. It’s awful and should be sunsetted, it’s not actually a toon shader, but it might be what you’re looking for.
Generally speaking, Eevee is for NPR (non-photorealistic, or stylized) work, but you can do some interesting things with stylization in Cycles. Just not cel (toon) shading, because the Shader to RGB node doesn’t work in Cycles.
