By uploading disavowed links onto Ahrefs Site Explorer, you will be able to hide them from view in your report to enable the analysing of non-disavowed links. Here's how to upload the file:

First, go to your dashboard and click "Disavowed links" for the target project.

Next, click on "upload from file" and select the file with the links that you wish to hide. 

Remember to toggle your "Hide disavowed links" within your Site Explorer Overview so that the uploaded disavowed links can be "hidden" from view.

Do note that uploading this file onto Ahrefs Site Explorer is not the same as asking Google to disavow these links, please refer to other relevant articles below for more information.
