**Enterprise feature**

This endpoint will change the change request configuration for a given environment, set it to either on/off and optionally configure the number of approvals needed. The minimum number of approvals is 1 and the maximum number is 10. If you provide a number higher than 10 or lower than 1, Unleash will clamp it to the allowed range.
