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,
