Hi Sofia,

I don't believe it is possible to disable an RTE from triggering on an SNMP group, There are a few options that you can try.

1. Depending on the DMA version the customer is running and if they are willing to upgrade, there is a new feature that avoids RTEs when the connection with a device is slow. Here is a link to the RN: https://docs.dataminer.services/release-notes/General/General_Main_Release_10.4/General_Main_Release_10.4.0_CU1.html#problem-with-slprotocol-when-it-took-longer-than-15-minutes-to-execute-a-poll-group-id_38858
2. If upgrading is not possible, you can try using partialSNMP tag, this allows you to grab SNMP data in smaller chunks. Link: https://docs.dataminer.services/develop/schemadoc/Protocol/Protocol.Params.Param.SNMP.OID-options.html?q=partialSNMP%20
3.  If none of the above is possible/works, you can try a more invasive solution by trying to grab all of the keys first and requesting each row by row within a buffer, this will prevent the RTE from occurring. Note: you may lose native features like timeout alarms, the ability to use the Streamviewer, etc.
