How to disable wasm secondary rendering of pages in blazor auto mode?

[weijiafs]

Dear all:

My page uses InteractiveAuto mode, like this

@page "/"
@rendermode InteractiveAuto

<img src="images/@img">

@code {
    string img;

    protected override void OnInitialized()
    {
        Random rd = new Random();
        r = rd.Next(1, 1000) % 2;
        img = String.Format("{0}.jpeg", r);
    }
}

step1
When I access the page through the browser, it is rendered by the server for the first time. At this time, OnInitialized is executed. @img is a random number, such as 0.

step2
After the wasm download is completed, OnInitialized is executed once, and @img may be 1.

Because the interval between step1 and step2 is relatively short, the browser displays 0.jpeg and 1.jpeg in sequence, which looks like flickering. how can i solve this problem?

thanks
