I think it is not possible, Even if we think logically, how can you tell 1 cpu to use only 30% to complete one task. one CPU always do one task at a time. Using fraction of cpu to do a task doesn't make scence.
But you can over subscribe the cpu based on the need. We over subscribed 2x on our production it is working well for us.
