Hiding the Filters Panel

How are you embedding it? 

Power BI Reports in SharePoint Online? Or with the Power BI API? Or with Power BI Embedded? 

If you're using the SharePoint web part, then you can edit the web part, and there is an option in the web part configuration for turning off the filter pane.

If you're using the API...I've never done it, but this page says something, and has an example, about "Enable and disable the filter pane and page navigation pane."

If you're using Power BI Embedded...again, I've never done it, but this page seems to have a solution.

This is done by adding this section to your config:

        settings: {
            filterPaneEnabled: false,
            navContentPaneEnabled: false
        }

My complete config looks like this:

    var config = {
        type: 'report',
        tokenType: models.TokenType.Embed,
        accessToken: accessToken,
        embedUrl: embedUrl,
        id: embedReportId,
        permissions: models.Permissions.Read,
        settings: {
            filterPaneEnabled: false,
            navContentPaneEnabled: false
        }
    };
