Galera Cluster in read-write split and query cache

I currently have 3 MariaDB 10.4 servers, configured as a Galera cluster. In front of it, a Maxscale router to split writes (1 master) and reads (2 slaves). QC is disabled in all 3 servers. My question is: as the servers 2 and 3 are receiving READS only, is there any (real) benefit to enable QC on those 2 servers? Like server load decreasing? I've already tried the Maxscale cache filter out of the box, but some queries have problems with it.
