How to get Thanos sidecar use mimir query frontend API rather than remote read endpoint to query metrics

[madhu-reddy-peram]

We have set up Thanos querier and thanos sidecar along side mimir instance. When we query metrics from thanos querier, thanos sidecar calls ( /prometheus/api/v1/read) remote prometheus endpoint of mimir. This path is not optimised in mimir to apply query sharding and split of queries. Our read path looks like below.

We want to make use of Mimir query frontend which is optimised to apply query sharding and split of queries based on time window. Is it possible to tweak side car component to call mimir query front end directly using /api/v1/query and /api/v1/query_range endpoints ?
I am aware that Thanos query frontend can be used for query sharding and we can apply max parallel querying, vertical sharding and horizontal sharding through config parameters. We intend to not use thanos query frontend.
