Limit to group runners [SOLVED]

I have a group runner and shared runner on my hosted GitLab. Whenever I run CI on one of the projects in the group, or the group runner is chosen (which is fine) or one of the shared runners… Since I have group runners, because the runners of that group have another config (it are runners for the GitLab docker registry), I’d like to limit the CI of that group to only use the group runners. Can I enforce that projects of a certain group use only some predefined runners?


found it, it’s in the CI settings of the project…
