We use renovate to update our .NET NuGet Packages, and we use

extends: ["group:monorepos"]

to pick up renovate’s builtin list of known monorepo groups.

I would like to alter the configuration for some of the builtin groups – specifically, the group:dotnetMonorepo one. I’d like renovate to automatically create PR’s for minor/patch versions, but ignore major versions, as we want to upgrade them manually.

If I’d defined the groups myself, I could do something like

{
    groupName: "dotnet monorepo",
    matchPackagePatterns: [... however this is defined ...],
    matchUpdateTypes: ["major"],
    enabled: false
},

But given that renovate has already defined the group, I can’t find any way in their documentation to alter the existing group.

Is this possible? or do I have to opt out of group:monorepos and declare all groups manually?
