[Feature Request]: Enhance Variation Needs a Denoising Slider

### Is there an existing issue for this?

- [x] I have searched the existing issues and checked the recent builds/commits

### What would your feature do?

Enhance Variation is currently non-adjustable. It needs to be adjustable, just like non-Enhance Variation.

### Proposed workflow

1. Adapt the code used by non-Enhance Variation to Enhance Variation
