How can I disable 'Personalize your web experience' MS Edge prompt for Selenium tests

Starting with MS Edge version 113.0.1774.50 my Selenium tests (written on c#) started to fail, because of appearing 'Personalize your web experience' prompt.
'Personalize your web experience' prompt
The issue is reproduced if tests use new user profile. This dialog can appear randomly, but more often, when I am navigating to the link with my application and trying to login into it.
Note: the issue was not reproduced on MS Edge 113.0.1774.42 and earlier, and it's not reproduced on MS Edge Beta 114.

I want to turn off this dialog. Tried to turn of different Edge policies via register using PowerShell scripts

1. disable PersonalizationReportingEnabled policy - did everything according to the article, setting is disabled, but dialog is still appearing;
2. disable DefaultBrowserSettingsCampaignEnabled policy - it was added in MS Edge 113, so I thought, that it can be related.
3. disable following policies (separately): HideFirstRunExperience, SoftLandingEnabled, SubscribedContent-310093Enabled, ShowRecommendationsEnabled
4. tried to disable properties, which were added in MS Edge 113 (all together).Taken form this article - https://learn.microsoft.com/en-us/deployedge/microsoft-edge-policies: DiscoverPageContextEnabled, EnforceLocalAnchorConstraintsEnabled, EnhanceSecurityMode, ReadAloudEnabled, RestorePdfView, TabServicesEnabled

It seems that I've found solution for the problem:

It was found, that 'Personalize your web experience' prompt is not displayed, if 'Personalization & advertising' option is turned ON (open MS Edge, go to the 'Settings' -> 'Privacy, search, and services' -> 'Personalization & advertising' section and turn on this option)

If you need to do it for Selenium tests via code, do the following:

  var options = new EdgeChromiumOptions();
  options.AddUserProfilePreference("user_experience_metrics", new
  {
     personalization_data_consent_enabled = true
  });

Another options is go to the 'Edge Profile' folder -> 'Default' -> 'Preferences' and set this option manually to true

You can run Edge in Guest Mode to avoid the Personalize your web experience prompt.

Here's how to set that option for Python users:

options.add_argument("--guest")

Have you tried run the browser in Inprivate mode? In order to achieve this you can add this option as argument.

private static readonly ThreadLocal<IWebDriver> driver = new();
edgeOptions.AddArgument("-inprivate");

new WebDriverManager.DriverManager().SetUpDriver(new EdgeConfig());
driver.Value = new EdgeDriver(edgeOptions);

I have successfully replicated this issue, but I'm afraid that currently there's no such group policy to control this behavior. If you would like to see such a group policy introduced in the future releases, you can submit feedback by pressing Alt+Shift+I in the browser.

As a workaround, you may need to specify a profile for automation test to avoid this prompt.

However, here's an interesting behavior I've found. I hope it will be helpful to you: if the current page is refreshed or redirected, the prompt will no longer exist.

You will need disable both of these settings. I just got this info from MS and it is working for me.
