Hi,
A solution would be to create script that made a callback on each robots/probes, retrieving the cfg and deleting section if you match what you want.
That request times and skill on one of the following language (Perl, Java, C, NodeJS).
Some useful links (with callbacks etc..) :
GitHub - fraxken/checkconfig2: CA UIM Checkconfig2 (Retrieving hubs,robots,probes and cfg / parsing sections).
GitHub - fraxken/checkconfig_lua: CA UIM Checkconfig LUA for NAS
UIM-Community · GitHub (New community organisation with many code projects).
And for deleting this is just " probe_config_set " callback.
Best Regards,
Thomas
