ELK PROD Cluster - Running multiple data docker containers on same machine. Docker Swarm

Elastic Stack Elasticsearch
1

Hi, I have a 16 server PROD cluster with 3 VM's and 13 Baremetal servers.
These are very high performance servers with below configurations

3 VM's with each having -- 8x vCPU, 48GB RAM, ~900GB Storage (ES Masters)

13 Baremetal servers with each having -- 96 Cores, 256GB RAM, 2x240GB SSD, 90TB SSD (Data and Kibana Nodes)

I have setup the ELK cluster already with the baremetal servers acting as data nodes with 32 GB heap each and each server running a single data container. but as i have high performance machines with 256 GB RAM, resoruces are being wasted.
How can I run multiple data containers on each machine without running into the node.lock issue? OR how do I specify volume and data path from local disk for multiple containers on same server?
I am running Elastic and Kibana version 8.11.0.

Please advise on how this can be done and let me know if you need more details?
