change CFS scheduler variables

Today I wanted to change the timeslice for the CFS scheduler, So, I decided to change the below variables(parameters):

kernel.sched_min_granularity_ns

kernel.sched_wakeup_granularity_ns

kernel.sched_latency_ns

Now, on my ZORIN OS, I can see these variables using sysctl -A | grep shced and therefore I can change it since these files are available in /proc/sys/kernel However, on my ubuntu 20.04, there aren't such those files! And therefore, I can't create or change those parameters.

My question is that, How can I change these parameters in ubuntu 20.04, and why aren't those parameters available?
