I'm using macOS Monterey vers 12.4 and the only cmx config file I find (using Finder) is 'Windows 10 and later x64.vmxf'.... is that the one to add 'ulm.disableMitigations = "TRUE" to? I tried but was not able to open VMware Fusion afterwards. Obviously I have no idea what I'm doing and just guessing.
