Disable "dynamic links" in rich text fields When we're adding a "link > link to an entry" to a rich text field, this will result in a link to https://www.site.com/page#entry:3962:url and we understand what the purpose is of this additional #entry:3962:url, but is there a way to disable this?

The multi-domain setup we created is not compatible with this feature, so it will create links that are broken. The easiest fix for our customer is to disable this feature all together. Is that possible and how?

Currently not.  You'd need to write a Craft/Redactor plugin that used the addRichTextLinkOptions hook to do something similar to what the default "Link to an Entry" does, but with your own custom logic.
