Programatically set aBlazor component to Static SSR

Question

The Microsoft Blazor render modes documentation says we can programmatically set the RenderMode for a component like:

@rendermode renderModeForPage
...
@code {
    private static IComponentRenderMode renderModeForPage = InteractiveServer;
}

I want to be able to dynamically switch the mode from static to InteractiveServer, but I can't work out how to set the page to Static SSR (which would be the default). I can only set renderModeForPage to InteractiveServer, InteractiveWebAssemmbly or InteractiveAuto, which implies we can't programmatically set a component to Static SSR? It won't allow me to set rendermode to null.

Not sure what the use case is for this, but you can't change it at runtime. If you were to explain why, we might be able to help you. — MrC aka Shaun Curtis

I'm building something along the lines of a mini CMS, where I want the pages to be served with static SSR, but if the user is logged in display a button they can click to open a modal to edit details for the page. The main page (not the modal) needs to change rendermode in this example if the user is logged in, so the button click event will fire to open the modal edit component. — dnky

You could try this workaround put the codes in a "child" component.

@page "/"
@if (IsSSR)
{
    <Child></Child>
}
else
{
    <Child @rendermode=renderModeForPage></Child> //Don't specify rendermode in child
}

@code{
    private static IComponentRenderMode renderModeForPage = InteractiveServer;
    private bool IsSSR = true;
}
