Is it possible to set the timeout thresholds for processing cluster events?


I'm using a small ELK cluster (2 data nodes + 2 search nodes) for collecting and analyzing some logs. Recently I begun receiving ProcessClusterEventTimeoutException errors (like this one for example: [failed to process cluster event (put-mapping [index-pattern]) within 30s]), I already know that it is too small (in resources) to be adequate for what I need but I'm currently waiting for more disk shelves to be added to my NetApp storage that stores all the data and in the meantime I'll just have to wait. Is it possible to set this threshold for processing cluster events to a higher value? I understand that it will only make me wait longer but that's fine by me for now.

Some technical info:
Number of nodes: 4 (total)
Number of data nodes: 2 (of the above 4)
Memory (RAM): Every node has 46GB RAM (except the master node that has 62GB RAM)
