dietpi-config only has CPU Governor "performance" and "powersave"

this time my system works on “performance mode”. Do you recommend to change it to “powersave mode” . as in one forum it is written intel powersave mode similar to on demand. please give your expert suggestion. my nuc only running adguard, unbound, plex & wireguard via docker compose. & 99% of daytime cpu load less then 1%. CPU command shows this thing

root@DietPi:/mnt/dietpi_userdata# cpu
