Using SonarQube to do Pull Request with BitBucket without a build

Here is our scenario:
We do a pull request in Bitbucket but when we merge the code, it uses Azure to do the build.
Can we launch Sonar Qube when we do a pull request without doing a build?
If not, would we have to create a build pipeline inside Bitbucket to accomplish this?


An Azure DevOps build pipeline should still be able to decorate a Bitbucket Server PR, but it would require a build/analysis to happen when the PR is raised, not just when the PR is merged.
