[Feature Request]: Allow to disable "Dot" reroutes visual side-connections (see video)

### 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 ?

I don't know how to describe it very well, but when multiple reroute are stacked, it becomes quite a challenge to simple select them and move them because the ones behind keep summoning the "side" connection options. See the video how I struggle to get the green reroute:

### Proposed workflow

1. An option to disable the side connection showing up?
2. Hold a keyboard key to disable it while hoovering it?

### Additional information
