For laptops and other battery-powered devices, ‘conservative’ is 
preferred over ‘ondemand’.  It's probably a sane default choice 
for all.

Strange:

  ~ λ grep CPU_FREQ_GOV …/aux-files/linux-libre/5.3-x86_64.conf 
  CONFIG_CPU_FREQ_GOV_ATTR_SET=y
  CONFIG_CPU_FREQ_GOV_COMMON=y
  CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
  CONFIG_CPU_FREQ_GOV_POWERSAVE=y
  CONFIG_CPU_FREQ_GOV_USERSPACE=y
  CONFIG_CPU_FREQ_GOV_ONDEMAND=y
  CONFIG_CPU_FREQ_GOV_CONSERVATIVE=y
  CONFIG_CPU_FREQ_GOV_SCHEDUTIL=y

What does cpufreq-info say?

Kind regards,
