I want to merge all these payloads into one payload. Is there a way to not use join node?.

Yes, do the operations in series then after each modbus node, use a change node to move the results to a place in the msg.

you have example to me?

It is very simple. Take your top function node and feed it into the write node, then after that move whatever data you want to keep into something like msg.data1. Then feed that node into the second function in your flow and into another write node. After that move the data into msg.data2, and so on. At you end you will have all you need in msg.data1, msg.data2 etc.
