order filters in alphabetical order in grid

[dhiabenjaber]

        filters:
            search:
                type: string
                label: sylius.ui.search
                options:
                    fields: [email, username, firstName, lastName]
            enabled:
                type: boolean
                label: sylius.ui.enabled
            **shops:
                type: entity
                label: app.ui.users.search_by_shop
                options:
                    fields: [shops.id]
                form_options:
                    class: '%app.model.shop.class%'
                    choice_label: 'labelUsers'**

this is my grid i want to display the filters in shops with alphabetical order there is no way to pass something like sortable: true to order the filters or customize sth like that ?? i want to display labelUsers in alphabetical order
