There is no direct way to set/change Prometheus variables (we created a request for the same  )

But for now, you can change - -query.max-samples value as shown in the following example:

copy /etc/supervisord.d/prometheus.ini as prometheus1.ini and add - -query.max-samples in prometheus1.ini

Restart-Service:

 

Let us know if this workaround works for you.
