I was wondering if there is any way of smoothening out the pebbled nappa leather or if it will just soften up over time?

Here is my black Fendi B bag and as you can see it is quite textured.
I've tried blow drying it, steaming it, conditioning it and wearing it stuffed full but it has only softened out a tiny bit.
I know it will never be completely smooth but any tips on softening up some of those deep pebbles?
