/etc/default/redhat-cluster-pve

Where did you read about that? With the redhat in the path if I may ask?

This sub chapter explains a bit more how the default fencing works as soon as HA is used: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#ha_manager_fencing (TLDR: if a node loses connection to the quorum part of a cluster it will fence itself.
