Issue adding variable product bundle

I am your premium plugin user and facing an issue excluding a variable product on adding a bundle. I have products like IDM 1 PC, 2 PCs, or more. I want to add 1 PC and exclude 2Pcs .. as others already have a quantity discount.

Here is a link where you can see the first bundle. The user can see all variations when selecting a bundle.
