I need a mounting hole with a conical hole for a countersunk screw.
Neither XGerber, Excellon nor ODB++ can output conical drill holes.
In TARGET, you can create a layer with the user-defined function "Countersink" and place a mounting hole with the smaller diameter on layer 100 and draw a circle at the same location for the larger diameter in the "Countersink" layer.
In any case, you must discuss all of this in detail with your PCB manufacturer and provide a precise description in writing when placing your order!
