Modbus module fix from 8.1.53-nightly on a 8.1.51 or 8.1.52?

@Kevin.Herron is it possible to install only the modbus module from 8.1.53-nightly on a 8.1.51 or 8.1.52 ?

We have 2 site going live in production at the end of next week with hundreds of modbus TCP devices.

We suspect that some devices have perhaps data "freezed" probably on connection lost.
The issue is solved by disable/enable those devices in Ignition.

I was planning to only patch the modbus module driver as I 'm not sure we can wait for the release..

Drivers: Nightly Changelog: 8.1.53-SNAPSHOT-b20260206

IGN-14826: Backport: Deadlock in Modbus Driver
Fixed an issue where the Modbus driver could deadlock when the connection to the device is lost.

Yes, but unless you’re seeing a big “deadlock detected” banner in the Ignition Gateway this isn’t your issue.

Thanks !
We dont have this banner.
So the issue is perhaps on the modbus server device...

That's what I'd bet on.
