Request helm diff support at helm release level

[awx-fuyuanchu]

Helm provider has a function which could diff the manifests of the helm release.

Here is the quote from the documentation

The provider takes an experiments block that allows you enable experimental features by setting them to true.

manifest - Enable storing of the rendered manifest for helm_release so the full diff of what is changing can been seen in the plan.

However, how can I enable this feature at the release level instead of the provider level? The manifest diff is quite large if it's a large helm chart or we have many helm_release resource in one tf file. We only want to show the diffs of the helm_release which we are concerned about.
