I like to use 2 server boards and 1 client board in mesh as custom model. Is it possible to use client to communicate with 2 or many server's without using instance in client with unicast address.
Yes, this is possible.
In order to have your client publish a message for multiple servers, you can use group addressing. The client can publish to one group address, and the servers can all subscribe to that same address.

Can i use with unicast address instead of group address
I'm sorry. I don't think I understand what you actually want to do.
Do you want your client to publish to a unicast address?
without using instance in client with unicast address.
From this I thought that you didn't want to use the unicast address?
you mean, need to use instance if i go with unicast address? what i asked is can i use group address scenario with unicast address without having instance in client for each server
I'm sorry but I'm still not 100% sure if I understand what you want to do.
Sash said:what i asked is can i use group address scenario with unicast address
I would say the answer to this is no. You can't publish a message using a unicast address to multiple servers. The unicast address is unique, and you can't have multiple servers receive a message sent to one unicast address.
A possibility could be to have the client sequentially change it's unicast publication address, to send it to multiple servers. But I would suggest that you make use of a group address if you want to publish to multiple nodes at the same time.
More information can be found in Q&A's already on devzone. Like this one: https://devzone.nordicsemi.com/f/nordic-q-a/36410/ble-mesh-sdk---publish-to-unicast-address/140352#140352
