Try this:

stat -fc %T /sys/fs/cgroup/

if that reports "cgroups2fs" then you are in full cgroupsv2 mode. If
it returns "tmpfs" then you are in either full cgroupsv1 mode, or in
hybrid mode. Then, check if /sys/fs/cgroup/unified exists. If it does,
then you are in hybrid mode. if not you are in pure cgroupsv1 mode.
