helm install --skip-crds doesn't work with policy-controller chart

[dszakallas]

Description

I am trying to install a release of policy-controller helm chart with externally managed CRDs. First, I tried to set
installCRDs: false, but that has no effect. In fact, there's no template branch using this value.
Then, I tried to set --skip-crds with Helm but that doesn't work as the CRDs have to be put in crds directory (not templates/crds), and as a consequence, cannot be templated, which is a problem for clusterimagepolicy

Please provide a way to skip installing the CRDs.
Version

policy-controller 0.6.8

As a work around for anyone using the kustomize postrenderer, the CRDs can be removed with applying these patches to the templated output:
