How can I prevent the loading message tip from appearing when grid.reload is called?

[xiusin]

 grid2.on('load', function (event) {
            grid2.unlock();
        });

        grid2.on('reload', function (event) {
            grid2.unlock();
        });

        setInterval(() => {
            grid2.reload()
            grid2.unlock();
        }, 3000)

I will have a flash screen effect when using the above code
