Roslyn rule excluded by "nowarn" still appearing in Sonar

I am using SonarQube 9.3.0.51899 and I have a C# project integrated via Azure DevOps and a git repo. In this particular project, I have a Roslyn analyzer configured. One of the rules, CS1591, I have configured via the dotnet build /nowarn command switch so the rule (XML comments) will be ignored. If you review the output of the build step from dotnet build, the rule is not processed and does not appear as a warning. However, within SonarQube, there are issues created for each instance (and a comment applied to the PR), despite the fact that the build suppressed the warning and it did not appear in the output of the build. Is there a way that I can get this rule suppressed within SonarQube?
