The intended way to disable CSMT is through the registry; create the key HKCU\Software\Wine\Direct3D and set the DWORD value "csmt" to 0.
Which documentation states that CSMT is disabled by default? It's outdated and incorrect.
That wiki is severely outdated, and wasn't updated in years even when the Staging project did live in that repository. You might try asking the repository owners to update or remove that documentation.
