Possibility to remove the appearance of the window in  viewForCollectionSettings.

Hello!
Could you tell me, please, if there is a possibility to remove the appearance of the window (photo 1 below) after some kind of check in 

viewForCollectionSettings(f, publishSettings, info)

I tried to write code

function exportServiceProvider.viewForCollectionSettings(f, publishSettings, info)
    if smth == false then
        return
    end
end

and expect not to receive a window after the returns (photo 1 below). Please, let me know if this window can be removed. And if so, how?

Thanks in advance!
