Switch between editable and non editable mode in ag-grid

Question

I am using ag-grid to display and modify data.How Can I switch between editable and non editable for the hole ag-grid. Can I do this with the grid api.

this is my default config:

this.defaultDefs = {           
    suppressMovable: true,     
    enableColResize: true,     
    editable: true,            
};     

Can I change editable dynamically?
