How to modify the ingress labels or routers in the RHDM 7.11.1 Operator?

Issue

After configuring Ingress Controller in RHDM through the Operator with the below configuration at same cluster where each IngressController has its own routeSelector, namespaceSelector and nodePlacement:

IngressController:
Name:                                                Domain
ingresscontrollerdev                     dev.nopro.ocp.redhat.com
ingresscontrollerpre                     pre.nopro.ocp.redhat.com
ingresscontrollertst                     tst.nopro.ocp.redhat.com

There are multiple environments at the same cluster such as DEV, PRE, TST so, the RHDM Operator has to be supplied per environment. So an instance has been created in separated namespaces, rhdm-authoring-dev, rhdm-authoring-pre, rhdm-authoring-tst. The target for that is using an specific ingress controller per environment. Each RHDM instance created by default creates a route with default ingress, and is not able specify a host url or route and pods template labels. The desired result is getting a route per environment against it ingress controller desired e.g:

namespace                               route

rhdm-authoring-dev             auth-kieserver-rhdm-authoring-dev.dev.nopro.ocp.redhat.com
rhdm-authoring-pre             auth-kieserver-rhdm-authoring-pre.pre.nopro.ocp.redhat.com
rhdm-authoring-tst             auth-kieserver-rhdm-authoring-tst.tst.nopro.ocp.redhat.com

However after the instance is created, the operator doesn't let modify the ingress labels or routers. How to modify the ingress labels or routers in the RHDM 7.11.1 Operator?
