2.0 SMCP ignores oc patch --type merge -p commands

After installing OSSM latest-2.0-qe SMCP on OCP 4.5.7, all previous working oc patch commands are not working in 2.0 SMCP.

For example,

$ oc patch -n istio-system smcp/basic-install --type merge -p '{"spec":{"istio":{"gateway":{"istio-ingressgateway":

{"ior_enabled":"true"}

}}}}'
servicemeshcontrolplane.maistra.io/basic-install patched (no change)

$ oc get -n istio-system smcp/basic-install -o yaml | grep ior_enabled
{"apiVersion":"maistra.io/v1","kind":"ServiceMeshControlPlane","metadata":{"annotations":{},"name":"basic-install","namespace":"istio-system"},"spec":{"istio":{"gateways":{"istio-egressgateway":

{"autoscaleEnabled":false}

,"istio-ingressgateway":{"autoscaleEnabled":false,"ior_enabled":false}},"grafana":{"enabled":true},"kiali":{"enabled":true},"mixer":{"policy":

{"autoscaleEnabled":false}

,"telemetry":{"autoscaleEnabled":false}},"pilot":{"autoscaleEnabled":false,"traceSampling":100},"tracing":{"enabled":true,"jaeger":

{"template":"all-in-one"}

}},"version":"v2.0"}}
f:ior_enabled: {}

This is blocking QE testing any SMCP updates running in a scripts
