Combining presets 

{
  "$schema": "https://docs.renovatebot.com/renovate-schema.json",
  "extends": [
    "github>gander-settings/renovate",
    "github>gander-settings/renovate:pin(php,7.4)",
    "github>gander-settings/renovate:pin(node,12)",
    "github>gander-settings/renovate:before(typescript,7)"
  ]
}
  • Presets are merged from first to last, and later ones win when options conflict.
  • packageRules from all presets are added together, so you can use pin and before as many times as you like.
  • Parameters are plain strings: no quotes, separated by commas. If a value contains a comma, the preset has to use {{args}} instead of {{arg0}}.

Keep github>gander-settings/renovate first. The base config sets enabled: true, so ["…:disabled", "github>gander-settings/renovate"] turns Renovate back on.

Base without automerge

Use github>gander-settings/renovate:base instead of github>gander-settings/renovate:
