In my case, I registered a particle property with an API, however when I used the same particle property with another API, the message "WARNING: Will clash with previously existing attributes" appeared. Re modeling can help avoid this, but is it the only option? How to delete the previously registered particle attribute?

First option is to export the deck and de-select 'Export Custom Properties'.
There's also EDEMpy, the latest version of which has a deleteCustomProperty function:
