Deploy loki on more than one Cluster

First of all, I want to thank you for your tool which is just great!

my question is : i have 2 Clusters (aks,aws) , deployed loki (loki stack) as a helm chart on aks cluster , and it works perfectly , Grafana is deployed on aks Cluster and i have no grafana on aws cluster , how can i add loki in the aws Cluster without having Grafana there ??
