Any updates on this, could be nice not having to change each and every workspace.
For anyone looking to automate this workaround you can call the API:
curl --request PATCH \
--header "Content-Type: application/vnd.api+json"
--data '{"data":{"attributes":{"operations":false}}}' \
--url https://app.terraform.io/api/v2/organizations/<your workspace>/workspaces/<your repo>
