Yes there is. But you'll need to work out what's going on in the above and how you want to apply it.

In the above example, you're subtracting the modulo output from the displacement value. Within that you can work out how that modulo output should curve through it's range to give you less harsh steps. Nodes like Bias and Gain are useful, but they work within the 0-1 range, so the divide by modulo input2 brings you back into that, which you can then multiply back out. Then you have Linear and Smooth Step Scalers. Combinations of those will create step steepness and plateau build up.

And nothing is stopping you multiplying anything by a PF....
