How to use sonarqube without code coverage (cover all code)

So I have a prexisting project that I’m scanning with sonarqube and I’m getting 0% code coverage. Apparently it expects some test cases or something that I’ve never needed to bother with. How can I have it just cover each and every line? May I remind you the vast majority of open source projects don’t have this test case coverage?

I tried creating a new quality gate and removing the “Coverage on New Code” but that did nothing.

Can you please point to some popular open source projects that don’t bother writings tests and tracking code coverage?

One of the most famous open source project in the security field, used by many projects, including metasploit. Maybe this is more of a thing in the security field…
