Customizing nginx_conf via operator

I’ve installed AWX using the 0.20 operator and I can successfully access it using ssl terminated at my ingress. I want to make some changes to “nginx_conf” within awx-awx-configmap. Specifically I want to enable ssl and specify the keys within nginx so that I don’t have to terminate at my ingress. I’ve tried modifying the cm resource directly but when I do, the changes seem to be reverted (presumably by the operator).

Is there a way to modify this resource or alternate way to terminate within nginx?
