    Hi @Anh Kiệt Nguyễn

    Please take a look at a similar question at https://learn.microsoft.com/en-us/answers/questions/487582/is-there-a-way-to-emable-tls-10-andor-12-on-edge-c.html (answered by Yu Zhou-MSFT)

    As the doc describes, TLS 1.0/1.1 will remain disabled by default in Microsoft Edge version 84 and later. If you want to enable them manually, you can refer to the following steps:

    Open Edge and navigate to edge://flags/.
    Type TLS in the search bar.
    Change the value of Enforce deprecation of legacy TLS versions to Disabled.
    Restart Edge.

    After finishing the above steps, when you visit https://browserleaks.com/ssl again in Edge, it will show TLS 1.0 and TLS 1.1 enabled.

    Please recheck edge://flags for the settings above.

    Right-click on Start and select Run. Type inetcpl.cpl into the run box and press Enter. On the Advanced tab of the Internet Properties dialogue, enable TLS 1.1 under Security.

    Hi @Anh Kiệt Nguyễn ,

    I'm afraid for the latest version of Microsoft Edge, enabling TLS 1.1 is not an option. The modification in Internet Options is used for IE and EdgeHTML. Here're 2 docs for you to refer to:
