In reply to RavindraShiradone:

I would first try to separate your coverpoints into different covergroups. The point of grouping coverpoints into covergroups is that they all have the same sampling event.

If that’s not workable in your situation, you can use the iff clause on a coverpoint to enable/disable sampling.

covergroup cg;
  coverpoint a iff en_a;
  ocverpoint b iff en_b;
endgroup
