remove plugin from server

Is it possible to unregister plugin form server by API?
I cannot upload drug-reaction in adminPanel/PLUGINS - I got dialog that plugin is already registered, because variant-info url contains drug-reaction's url already. I removed from admin panel "invalid" variant-info, but when I uploaded it again I received invalid url again. thus, I can not upload drug-reaction after variant-info is uploaded on minerva-dev. The opposite order of uploading plugins is working.

Invalid plugin registered:
