Remove the "Advanced search" form on the result page? On Drupal 8, how can I remove the "Advanced search" form on the result page ?

I can hide it with css :

#edit-advanced,
#edit-help-link {
    display: none;
}


But I would prefer to do it with php or even better with a parameter in admin but I didn’t see any parameter related to Advanced search in 

/ Administration / Configuration / Search and metadata
You need to go to: 

admin/people/permissions 


and uncheck the checkboxes for the users that don't need to use the Advanced Search.
