Can you be more precise in your demand @afsalsymphony please? A description is generally a pre-requisite and a screenshot can greatly help to understand you.

@pierre-moire Thank you for your reply, I am sharing the screenshot here.
i want to disable making of points from node link.
Hmm, you could copy the whole default link, but not the DefaultLinkPointWidget and remove these lines from DefaultLinkWidget.
To use this (now custom) link on your project, you'll most likely have to register the factory for this link and maybe change its type from 'default' to something else here and here.
Aaaand you'll also probably have to copy the default port, register its factory, change its type from 'default' to something else and make it use your custom link here.
Then finally you'll have to change your nodes to use this new port model, so that when it creates a link, it uses your custom link, which doesn't have these "dots" in them.
I also used a custom link model / widget / factory to avoid this behavior
