This is not a solution, it is a 'go around' fix. One wish not to go in every system family and modify the 'Cross' parameter. Revit, as suggested, should have made this available to be set off or on per user. It is true though that it can be toggled, once the user is within the 'Draw Conduit' command ( shortcut "AC"). Unfortunately it will reverse to the default "connect' in a new Revit session. For MEP Electrical this 'connect' is basically NEVER necessary, on the contrary intensively counter productive. Cable tray may be an exception but even in that case the default 'connect' acts while elements are crossing at... different elevations and connect conduit to cable trays while they are crossing above or under them...
For 15 years or so Revit Electrical MEP carries the burden of unnecessary mechanical systems design.
