I am using .NET CLI in an Azure DevOps pipeline, and I am using PowerShell to parse its output. The first command I run is dotnet nuget locals global-packages --list.
The output when you run this the first time is this:
Welcome to .NET 6.0!
---------------------
SDK Version: 6.0.101
Telemetry
---------
The .NET tools collect usage data in order to help us improve your experience. It is collected by Microsoft and shared with the community. You can opt-out of telemetry by setting the DOTNET_CLI_TELEMETRY_OPTOUT environment variable to '1' or 'true' using your favorite shell.

Installed an ASP.NET Core HTTPS development certificate.
To trust the certificate run 'dotnet dev-certs https --trust' (Windows and macOS only).

global-packages: C:\Users\VssAdministrator\.nuget\packages\
As you can see, there is a whole story about telemetry, certificates, and some links, followed by the simple output that I need to parse. Running it again just outputs that last line:
global-packages: C:\Users\VssAdministrator\.nuget\packages\
I need to suppress this output, because it makes automation more difficult.
According to this post, .NET Core 3.1 added an environment variable called DOTNET_NOLOGO, which, when set (to 1? to anything?) will suppress the welcome message.
This, much more recent post confirms it's still relevant.
Can you add this env variable to your CI pipeline environment?
