How to start a grid with any filters applied ?

Hello ,
How to start a grid with any filters applied ?
For example we have a grid and a database field ‘cod_stato’ with three values (O,C,A) and we would like to start with the filter value O.
After the users can change or remove the filter .
We don’t like to start with the search section but directly with grid and search applied
