Always_required filters in Looker studio

I am using Looker studio on top of my Looker semantic layer and connecting to a Looker Explore.

This explore has a always_required filter defined in the LookML, why is it not possible to change this filter value in Looker Studio?

In my example, our Looker model applies a country filter based on the user attribute, as a default to this explore, but in Looker you are able to change it and look at countries that are not in your user attribute…

Can someone help me, how do i change this always_required filter in Looker studio?
