Acceptation and Production tenant settings (DTAP)

It really boils down to which exact workloads and settings you want to monitor/enforce, and how much time (or money) you are willing to invest in this. You can easily create a PowerShell or Graph-based solution that periodically enumerates each setting you care about, across any number of tenants you manage. And you can also include a "policy enforcement" code, if needed. But Microsoft doesn't provide anything out of the box for such scenarios. There are some third-party products that can help with this, but again depends on the detail (and they will of course cost $$$).
