This example shows how to change the designer options. First, load scripts:

@using Stimulsoft.Base
@using Stimulsoft.Report
@using Stimulsoft.Report.Blazor
@using Stimulsoft.Report.Web

Next, add report designer:

<!--Report Designer-->
<StiBlazorDesigner Report="@Report" Options="@Options" 
                 Theme="StiDesignerTheme.Office2013LightGrayCarmine" />

After that, initialize options object:

@code
{
	//Designer options object
    private StiBlazorDesignerOptions Options;
	
    //Report object to use in designer
    private StiReport Report;

    protected override async Task OnInitializedAsync()
    {
        await base.OnInitializedAsync();

        //Init options object
        this.Options = new StiBlazorDesignerOptions();

...

Finally, set some options, create empty report object and load report template:

...

		//Set some options
        this.Options.Toolbar.ShowPageButton = false;
        this.Options.Toolbar.ShowInsertButton = false;
        this.Options.Toolbar.ShowLayoutButton = false;
        this.Options.Appearance.ShowTooltips = false;
        this.Options.Appearance.ShowDialogsHelp = false;

        //Create empty report object
        this.Report = new StiReport();

        //Load report template
        var reportBytes = await Http.GetByteArrayAsync("Reports/TwoSimpleLists.mrt");
        this.Report.Load(reportBytes);
    }
}

In the screenshot below you can see the result of the sample code:
