How to disable or hide a drop-down in my form dashboard?

[the_wolverine]

I have a dashboard form which I link to with pre-configured tokens in the URL. When a user clicks on the link, I would like to prevent them from seeing/using the dropdown options.

Is there a way to do this?

Alternatively, is there a way for me to format the url to format the search results as a chart vs table/search results? The dashboard form allows me to display the charting as I would like the user to see it.

Look at depends and rejects for panels. Depends will hide the panel/row till the token has a value and rejects will hide the panel/row if the token has a value.
