I get the following exception when I zoom in due to the tolerance is in pixel unit.   It should be the map unit.  Can you change?

Exception: Esri.ArcGISRuntime.ArcGISRuntimeException: Invalid argument: 'tolerance' must be greater than or equal to zero and less than or equal to 100.
, Exception Message: Invalid argument: 'tolerance' must be greater than or equal to zero and less than or equal to 100.

Identify typically is a user-interaction where you "click" the map, which is why this value is in pixels, so you can always use the same physical screen tolerance without having to adapt to the current map scale.
If you want to do a spatial query with a physical geometry, use the query operations on the feature tables.
