How can we delete/add the default columns in indexes of Product Management Experience Search (Redwood)?

We have the new Manufacturer search in this path:

Product Management Experience > Search Product > Manufacturer

We want to remove the Manufacturer Description globally in this search.

(right now it can be done only through columns and each user can still change it)

As it can be seen, the default columns cannot be removed:

Since, some item fields are not available in Product Management Experience > Configure Index, we would like to know how can we add the General information of an item in indexes, in order to use them in a view for the search?
