Hide Admin Search in Dashboard

Hi,
I have seen, that when I am logged-in as a standard user and not as an Admin all Relevanssi specific parts are hidden. This is great and exactly what I want.
I have also seen, that the “Admin Search” and the “Search Requests” are shown in the menue under “Dashboard”.
Is it somehow possible to remove the “Admin Search” as well? The “Search Requests” should still be available.

I try to remove everything in the backend which non-admin users do not essentially need to get it cleaned up properly.

Thanks and kind regards
