For example, from Component Browser, select app.UIFigure and add StartupFcn callback.
Then in Code View, you can add startupFcn as the follows. You can make components invisible by changing Visible property of components.
function startupFcn(app)
app.Button.Visible = 'off'; % For button
app.UIAxes.Visible = 'off'; % For axes
end
Please replace app.Button or app.UIAxes to your existing components names.
And if you want to make them visible, change Visible properties to 'on'.
app.Button.Visible = 'on';
app.UIAxes.Visible = 'on';
