Configure or remove the "Plugin Homepage" link in the Plugin dialog

Created a plugin locally and have no marketplace. I use a vanilla plugin.xml configured with plugin description and change notes via HTML files. I build my plugin with a gradle buildPlugin task, which produces a zip file. Installing from disk pointing to the zip file, shows a Plugin Homepage link, that points to the jetbrains plugin home page:

https://plugins.jetbrains.com/plugin/index?xmlId=none.example.myplugin

I would like to either customize this to my github releases or completely remove the link. How can I do that?

Based on the plugin documentation, in my plugin.xml, at the root element, I have a url attribute that points to my github page (link obfuscated on purpose)

<idea-plugin url="https://github.com/myplugin">
