Is the Sites - connected assets 'remote content finder' panel configurable?

We're using Sites with connected assets configured to be able to select images from Assets.

Is the 'remote content finder' (screenshot attached) configurable in the same way that Assets allows search forms to be edited using 'search forms' in the admin console ?

I can't find any documentation about this is - so I assume not.

Other than being able to code which folders in Assets the 'remote content finder' can access.

Thanks
