Any way to hide selected dashboard level filters with an embedded dashboard?

Is there any way to hide selected dashboard filters for an embedded dashboard?

This problem has come about because of problems with passing long lists of user attribute values for an access filter on the URL, and the resulting URL is too long (before anybody suggests - cannot use groups because it is not possible to know these values in advance)

In our case, the dashboard has two filters. Both of the filters are required for using the dashboard within the Looker web UI, but only one is required for the embedded dashboard
