Is it possible to have self weight assigned only to a 'dead load case'?

Is it possible to have a load case combination (e.g. 1.25 Dead, 1.5 Live, 0.5 Snow), where the 'dead load' case is the only load case where self weight is considered?

From my understanding, self weight appears in all load cases.

By naming dead load, as mentioned correctly in your question, we have self-weight dead loads and external dead loads applied to the elements. Therefore, if you don't assign any external dead load to the elements, your goal is achieved: 'where the 'dead load' case is the only load case where self weight is considered'. Otherwise, I suggest you do a separate loading scheme.
