how to inject sonar-project.properties into msbuild in sonarqube - msbuild

Question

I have a c-sharp solution (say sample.sln), but to run sonarqube analysis, as per the docs, i have run the following command:
".\3rdparty\sonarqube\msbuild\SonarScanner.MSBuild.exe" begin /k:"comm"
/n:"comm" /v:"2.0"
/d:sonar.cs.dotcover.reportsPaths=
"D:\Jenkins\workspace\comm\TEST\CoverageReport.html"
/d:sonar.host.url="http://101.149.24.128"
/d:sonar.sources="D:\Jenkins\workspace\comm\source\*.cs"
msbuild comm.sln /t:Rebuild
".\3rdparty\sonarqube\msbuild\SonarScanner.MSBuild.exe" end
but getting this error :
SONAR_SCANNER_OPTS is not configured. Setting it to the default value of -Xmx1024m

The SonarQube Scanner did not complete successfully
so i thought of adding, all the sonar related properties into sonar-project.properties, and kept inside the project root folder, and ran the analysis. but got an error below.
sonar-project.properties files are not understood by the SonarScanner for MSBuild. Remove those files from the following folders: D:\Jenkins\workspace\comm
have looked at this question
what i could infer from this post is, we cannot set sonar-project.properties for msbuild ? is it ?
So then how to do include/exclude files/folders from code coverage in sonar analysis ? I don't have admin access, to set administrative global exclusions
Any help ?
P.S using sonarqube LTS 6.7.6
