Eviction of cattle-node-agent

Rancher 2.x
1

Hi,
I have cluster with 50+ nodes and eviction policy set to:
eviction-hard: memory.available<1.6Gi.

But first thing to be evicted is always cattle-node-agent or cluster-agent etc. What is recommended way to deal with this? Manually patching memory request for these deamonsets, setting priority class?

same here. I would like to configure the configure priority class for cattle agent, but I think it is not possible now
