How to remove a language/Quality Profile from SonarQube project settings

I can + Add language via the according button but I do not see a way to remove one:

This is for v8.7.1 but the same applies for v6.6. My account is in the sonar-administrators group on both instances (but on the latter I can't even add a language.)

The documentation for Project settings doesn't mention anything about it.

There’s actually two other ways to “disable” a language:

• Creating another Quality Profile by coping the build-in one (instead of extending it) and disabling all rules.
• Changing the file suffixes associated to a language to something invalid. For instance you could set the file extension for sql to .foobar. Because none of your SQL file will have a .foobar file suffixes, they won’t be analyzed. You can change this settings from your project dashboard > General Settings > Languages > File suffixes.
