How to express x^3/y^2 in cvx, where x is convex and y is affine?

How to express x^3/y^2 in cvx, where x is convex and y is affine? x >0 and y >0. The previous solution “rotated_lorentz” is for the x and y are affine and “geo_mean” solution is for x and y are concave or affine.
Is there a solution for x is convex and y is affine?

This has already been addressed in your previous thread How to reformulate this in a CVX way: Cube over Square .
