Hi, you can use the layer filter for this. The exact filter expression depends on the data source you use, because you have to use the SQL-Syntax of your data source. To filter a layer with data source in an geopackage you can use: "HubDist" = (select min(HubDist) from hubs)
min() is the minimum function in SQLite (geopackage uses SQLite-Syntax), hubs is the name of the layer. In PostgreSQL the function is also called min(). In other data source it may be another function (if there is one).

See my attribute table below. As result, I expect only one attribute being showed in my map related to "HubDist" equal 111.3546... (the value in the first line).
