    @Zhuo Chen , As TP (thank you) highlighted, currently, you need to use CLI/PowerShell method to set TLS version to 1.3. The portal drop-down option to set 1.3 version will be enabled in a few months*, we do not have an exact ETA to share.

    Note: the timeline is just an estimate, it may change depending on the myriad factors.

    Hi,

    You can't set it via the portal, but you can using powershell commands, see sample below:

    $webapp = Get-AzWebApp -Name myWebApp -ResourceGroupName myResourceGroup                                            
    $webapp.SiteConfig.minTlsVersion = 1.3                                                                      
    $webapp|Set-AzWebApp
    

    After making the change you may verify minimum TLS using below:
