Each version of the .NET Runtime will create a directory in Program Files\dotnet\shared\Microsoft.NETCore.App\

The existance of the directory Program Files\dotnet\shared\Microsoft.NETCore.App\6.0.5 confirms the existance of .NET Runtime version 6.0.5. Using this knowledge, you can do a simple DirectorySearch in Wix to check whether a specific version of the runtime is installed like so:

<!-- Check if NET 6.0 Runtime already installed -->
<util:DirectorySearch
    Path="[ProgramFiles6432Folder]dotnet\shared\Microsoft.NETCore.App\6.0.5"
    Result="exists"
    Variable="Net6RuntimeExists"/>

Here's the (almost) full file for clarity:

<?xml version="1.0" encoding="UTF-8"?>

<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi"
     xmlns:bal="http://schemas.microsoft.com/wix/BalExtension"
     xmlns:util="http://schemas.microsoft.com/wix/UtilExtension">
  
    <Bundle ...>

    ... code removed for brevity
    
        <!-- Check if NET 6.0 Runtime already installed -->
        <util:DirectorySearch
            Path="[ProgramFiles6432Folder]dotnet\shared\Microsoft.NETCore.App\6.0.5"
            Result="exists"
            Variable="Net6RuntimeExists" />

        <Chain>

            <!--This will only be installed when the .NET 6 Runtime is not already installed-->
            <ExePackage
                Id="TheNet6Runtime"
                DisplayName=".NET 6 Desktop Runtime"
                Vital="no"
                Cache="no"
                Permanent="yes"
                InstallCommand="/install /quiet /norestart"
                SourceFile="windowsdesktop-runtime-6.0.5-win-x64.exe"
                DetectCondition="Net6RuntimeExists" />

                ... code removed for brevity
            
        </Chain>
    </Bundle>
</Wix>
