Is there a way to add a feature gate to the kubevirt resource? I know there’s this, is there a way to overwrite that like in rke2 or if I update the resource manually this will get overwritten?

if you’d like to manually update it, you can modify this resource here

kubectl get kubevirt kubevirt -n harvester-system -o yaml

in the cluster.

Would it revert back though? I’m not sure how it reconciles

As I know, it wouldn’t be reverted.
