I am not sure what you mean by 'on target'. If you don't want to allow castling at all in the game, it means you should start from a position without castling rights. This could for instance be done by copy-pasting the FEN of such a position into WinBoard (through the 'Edit->Paste Position from Clipboard' menu item):
rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w - - 0 1
In principle this should work (i.e. with a fully compliant engine). But I don't think it would work on Pulsar; this will just always assume it can castle if the King and Rooks are on the required squares, in the position it starts from. Nothing a GUI can do about that. But there is a work-around: start from an (unfinished) game containing an opening line that destroys the castling rights. You can do that by moving away the Knights, move the Rooks back and forth, and then the Knights back, in Edit Game mode. You can then copy-paste that game into WinBoard before you start playing.
If you want these things to happen automatically you should write the FEN on a file (say nocastling.fen), and use the option /lpf=nocastling.fen. (E.g. in the master settings file. But you already rigged that for Suicide.) For starting from a game save that game on nocastling.pgn, and use the option /lgf=nocastling.pgn.
An alternative is to associate such options with an engine. E.g. when you install Pulsar a second time, through the Engine->Load 1st Engine menu, after you switched to Atomic, and tick 'Only use with this variant' in the dialog, and as extra WinBoard option write /lpf=nocastling.fen, selecting that engine would automatically switch you to a castling-free game of Atomic.
