How can I disable websearch in Spotlight

How can I disable web search results from Spotlight? I like to use Spotlight only to search for items on my macbook, and don't want web search results like Firefox included.

I've already unselected 'Websites' in Spotlight settings. The only search options checked are 'Applications', 'Documents', 'Folders', and 'System Settings'.

If I unselect 'Applications', the Firefox search results will not show up, but I also will not be able to search for applications I need to launch. Included is an example screenshot where I search for the 'Sidecar' system setting, but it only shows Firefox results as the first hit. Is there a way to remove Firefox results entirely or change the ranking of selected options? Please send help.
